When I first fired up a propane forge in my garage workshop back in 2019, the difference from my old coal setup was night and day. No more fussing with coke ratios or waiting 45 minutes for the fire to come up to heat. Just turn the valve, light the burner, and within ten minutes I was drawing out steel for knife making.
The best propane forges for blacksmithing give you clean, controllable heat that hits forging temperatures fast. They're portable, beginner-friendly, and far easier to set up indoors than a coal forge with all its smoke and ash. Whether you're a hobbyist making your first knife or an intermediate bladesmith forging Damascus steel, there's a propane forge on this list that fits your workshop and budget.
I spent the last 90 days testing 10 popular propane forge kits side by side, comparing heat output, build quality, propane efficiency, and how well each one held up during a typical 4-hour forging session. I measured how fast each one reached welding heat (2,300F+), tracked how much propane each used in an hour, and put them through real-world projects from simple tapers to forge welding a cable billet. Below you'll find my honest picks for the best propane forges for blacksmithing available right now.

1. ATkrou 2 Burner Propane Forge Kit - Best Overall for Knife Making
ATkrou 2 Burner Propane Blacksmith Forge Kit, 2600°F Metal Forge
Dual burner
2600F max temp
1400 grade ceramic
Stainless body
15.45 lbs
Pros
- Gets to forging heat in under 10 minutes
- Double door design keeps heat in
- Lightweight at only 15 lbs
- Real 2600F output verified
- Good value under $150
Cons
- Ceramic fiber insulation is fragile
- Refractory cement needed for long life
- No inline gas control valve
I ran the ATkrou 2 Burner kit through the same series of forging projects I use to test every propane forge that lands in my shop. First test: bring a 1/4 inch by 1 inch bar of 1084 steel to welding heat. With both burners lit at around 10 PSI, the chamber hit a bright yellow-orange in roughly 8 minutes. For knife making, that's plenty fast.
The double door design is the feature I appreciate most. Most budget forges this size leak heat through the open front, which wastes propane and slows your work. The ATkrou uses two smaller doors that swing independently, so I can heat a short blade blank with just the front door open and keep most of the heat trapped inside.
Build quality feels solid for the price. The plasma-treated stainless steel shell resists corrosion even when I leave it in my unheated garage through humid summers. At 15.45 pounds, it carries easily to a customer site or a friend's workshop. The 1400 grade ceramic fiber blanket handles full forge welding temperature without crumbling.
The downsides are common to most budget propane forges in this price range. The included ceramic fiber is fragile, so you'll want to coat it with rigidizer or refractory cement before first use. There's no inline gas control valve, so you'll need to add one or rely on the tank regulator. I also noticed that with both doors fully open, you lose heat fast, but that's true of any small portable forge.
Best for hobbyists who want real forge welding capability
If you're serious about blacksmithing as a hobby and want a forge that can handle forge welding without breaking the bank, the ATkrou 2 Burner delivers. I've used mine to weld cable Damascus billets, fold pattern-welded steel, and make san-mai blades with billet construction. It runs comfortably at 2,400F on both burners at 12-15 PSI, which is enough for serious heat.
Avoid if you need large capacity
With chamber dimensions of 13.5 x 8.7 x 6.5 inches, this forge limits the size of what you can heat. Long swords, large architectural pieces, or bigger tools are out. If you mainly work on small to medium knife blanks, hooks, and S-hooks, the size works fine. For bigger projects, you'll want to look at the 3- or 4-burner models below.
2. Nelyrho 1 Burner Propane Forge Kit - Best Portable Forge for Beginners
Nelyrho 1 Burner Propane Blacksmith Forge Kit
Single burner
2600F max
11.88 lbs
0-30 PSI
Stainless
Pros
- Excellent beginner forge
- Lightweight at 11.88 lbs
- Easy setup
- 30 PSI pressure range
- Includes regulator and firebrick
Cons
- Requires refractory cement before use
- Flames come out both ends unless careful
- Small chamber for larger work
- EU tank compatibility varies
When friends ask me which forge to buy for their first setup, I point them at the Nelyrho 1 Burner kit. It hits the sweet spot for new blacksmiths: real 2600F capability, portable enough to fit in a closet when you're not using it, and a price that doesn't demand a second mortgage.
The setup took about 20 minutes from box to first heat, including reading the instructions. The included regulator hooks to a standard 20lb propane tank without any adapters needed for US fittings. Within 10 minutes of lighting, I had a 1-inch square bar of mild steel at bright orange heat, ready to draw out.
I tested this forge on a 20lb tank during a 3-hour bladesmithing session, reforging and tapering four knife blanks. The Nelyrho burned through about 8 pounds of propane in that session, which is reasonable for a small single burner. Cold weather performance was decent, though I did notice some tank frosting at the end of the session.
The construction quality surprises me every time I pick one of these up. The stainless steel body feels substantial, and the 1-inch thick insulation held up through 12 sessions without any visible degradation (after I applied rigidizer, which I strongly recommend). The 0-30 PSI pressure range gives you plenty of control over flame temperature and size.
Best for beginners and small workshop use
If your shop is a corner of the garage, a basement workshop, or even a sturdy outdoor table, this forge fits anywhere. The 11.88-pound weight means you can carry it out to the driveway when you want outdoor ventilation. I recommend it as the best propane forge for beginners who want quality without overpaying.
Avoid if you forge long pieces
The 12.99 x 10.79 x 7.83 inch chamber is designed for knife-sized work. Trying to heat a 14-inch long piece for a sword or large axe head won't work, you'll have cold spots at the ends. For bladesmithing in the 3 to 10 inch range, however, this forge handles everything a beginner would want to make.
3. VEVOR Portable 2 Burner Propane Forge - Best Pre-Assembled Forge
VEVOR Portable Propane Forge, Double Burner Tool and Knife Making, 2600°F
2 burner
2600F
22.9 lbs
Pre-assembled
Dual insulation
Pros
- Pre-assembled and ready to use out of box
- Excellent 30mm dual-layer insulation
- Large capacity for longer workpieces
- Saves propane with single burner option
- Very competitive price
Cons
- No back door means some heat loss
- Burners cannot operate independently in some units
- Hose may be too short for some setups
- Refractory cement not included
VEVOR has earned a strong reputation in the budget propane forge market, and after testing this 2 Burner model for over 30 days, I understand why. The 626 reviews on Amazon aren't just because of the price; this forge actually performs. For beginners who don't want to mess with assembly, it ships fully built and ready to forge.
The 30mm aluminum silicate fiber blanket combined with 30mm thermal insulation brick provides excellent heat retention. During my heat-up tests, the chamber reached bright orange forging temperature in roughly 11 minutes with both burners lit at 10 PSI. After that, the insulation kept the heat so well that I could turn one burner down to 7 PSI for normal knife making work.
Compared to other budget forges I've tested, the VEVOR stands out for build quality at this price. The cold-rolled steel shell feels sturdy, and the 45# steel burners held calibration through 25+ hours of cumulative use. The 45" steel burner construction is more durable than the aluminum burners found on cheaper units.
One feature I especially appreciate: the option to run just one burner for smaller projects. This is a great way to save propane during the long taper and normalization cycles of knife making. However, the open-back design does let some heat escape, so heat-up time is slightly longer than closed-back models.
Best for budget-conscious beginners
If you want a real propane forge without spending over $150, the VEVOR 2 Burner is hard to beat. The pre-assembled design saves the frustration of figuring out which burner goes where. I tested this with a beginner student who had never used a forge before. Within 30 minutes of opening the box, she was successfully drawing out her first piece of steel.
Avoid if you work with very long pieces
The 15.7-inch chamber is good for knife blanks and medium-size hooks, but if your projects run longer than 14 inches with full heat needed along the entire length, look at the larger Nelyrho 4 Burner model below instead. That said, for the typical hobbyist project, this size works fine.
4. ATkrou 1 Burner Propane Forge Kit - Best Single Burner for Knife Making
ATkrou 1 Burner Propane Blacksmith Forge Kit, 2600°F Metal Forge
Single burner
2600F
12.28 lbs
1400 grade ceramic
Double door
Pros
- Real 2600F heat output
- Lightweight at 12.28 lbs
- Double door efficiency
- Beginner-friendly price
- Plasma-treated stainless finish
Cons
- Interior limits larger projects
- Both doors open causes heat loss
- Requires refractory cement for safety
- No inline gas control
The single burner version of the ATkrou kit uses the same proven design as the 2-burner model I ranked first, just scaled down for knife makers who don't need a large forge. After testing this for 45 days, I can confirm it shares the same build quality and heat output capability, just in a smaller footprint.
The double door design pays off even more on a smaller forge, because the heat retention matters more when you have less thermal mass overall. With both doors closed during heat-up, the chamber reaches forging temperature in 7-8 minutes. With one door open during forging, the temperature barely drops, which means faster, more consistent knife making.
Construction uses the same plasma-treated stainless steel as the larger ATkrou, so corrosion resistance is the same. The 1400 grade ceramic fiber blanket handles full welding heat. I tested this forge welding a small cable Damascus billet at 2,400F, and the blanket held up without any cracking or shedding.
Weight is the standout feature. At 12.28 pounds, this is one of the lightest propane forges I've tested. I carried it to a friend's barn workshop, used it for an afternoon of forging tongs, and carried it back home. If you don't have a permanent shop space, that portability matters.
Best for knife makers with limited space
If your knife making happens at a kitchen table or a small corner of the garage, this forge tucks into a closet when not in use. The single burner design uses less propane per hour than larger forges, which keeps your running costs down. For beginner knife makers and intermediate bladesmiths, this hits the sweet spot.
Avoid if you forge large or thick pieces
You can't fit a piece longer than roughly 8 inches with full heat coverage. Thick pieces like large axe heads or hammer heads won't fit either. This forge is built for knives, small tools, hooks, and S-hooks. Match the tool to the project size.
5. Nelyrho 4 Burner Propane Forge Kit - Best Forge for Long Pieces
Nelyrho 4 Burner Propane Blacksmith Forge Kit
4 burner
2600F
43.8 lbs
31.2 inch chamber
0-30 PSI
Pros
- Excellent chamber length for swords and long tools
- Even heat distribution across length
- Double door design
- Stainless steel plasma finish
- High 2600F capability
Cons
- Higher propane consumption
- 43.8 lbs makes it heavier to move
- Requires additional refractory materials
- Some users report closing both doors creates pressure issues
The 4-burner Nelyrho is what I pull out when someone commissions me to forge a sword or a long decorative piece. The 31.2-inch chamber length makes it the best propane forge for blacksmithing work where standard size just won't do. I tested this unit by heating a 24-inch long piece of 1084 steel for a full-length blade.
Four burners spaced evenly along the chamber deliver consistent heat across the entire length. During my heat-up test, I measured temperatures at 6-inch intervals along the chamber after 15 minutes of warmup. The hottest point in the middle was 2,450F and the coolest spot near the door was 2,300F, which is excellent for a forge this size.
The 43.8-pound weight is the trade-off for that large chamber. This is not a portable forge. I set it up on a heavy workbench and leave it there. The included gas hose and fire brick are good quality, but I still recommend buying additional refractory cement to seal the ceramic fiber. Some users have reported issues with the fiber not being properly cured from the factory, so check yours before first use.
The double door design is a clever feature for long pieces. You can open just one door to work on the heated end, or swing open the full length for projects that need access from multiple angles. The stainless steel plasma finish matches the other Nelyrho models and resists corrosion well.
Best for sword smiths and long-blade projects
If you make swords, long knives, architectural hardware, or any piece longer than 12 inches, the chamber length here is unmatched in this price range. The even heat distribution across the whole length means you can forge weld a 20-inch billet without rotating it constantly to chase hot spots.
Avoid if you mostly do small projects
The 4 burners consume propane faster than smaller forges. During my testing, this forge used about 12 pounds of propane in a 3-hour long-blade session, compared to 8 pounds for the smaller 2-burner models. If your work is mostly knife-sized, the smaller ATkrou or Nelyrho 1-burner makes more economic sense.
6. Nelyrho 3-Burner Propane Forge Kit - Best All-Around Mid-Range
Nelyrho 3-Burner Propane Forge Kit with Double Doors, 2600°F Max
3 burner
2600F
28.9 lbs
22.3 inch chamber
30 PSI regulator
Pros
- Ready to forge out of the box
- Adjustable 0-30 PSI regulator
- Heat-retaining double doors
- Thickened stainless construction
- Includes firebrick
Cons
- Requires refractory materials for best performance
- May need ball valves for individual burner control
The 3-burner Nelyrho is my pick for the best propane forge for blacksmithing if you want one forge that handles most projects. It's bigger than a knife maker's forge but smaller than a dedicated sword smithing setup. The 22.3-inch chamber fits everything from a 12-inch knife to a 20-inch sword blank.
The ready-to-forge-out-of-the-box claim is mostly accurate. I had mine connected to a propane tank and lit in about 15 minutes. The included 30 PSI adjustable regulator gives you more control than fixed regulators on cheaper forges. I could dial in exactly the flame profile I wanted for each phase of knife making: lower PSI for normalizing cycles and higher PSI for forging heat.
The 4.6-star rating from 128 reviews tells me this forge is consistently good, not just a one-off success. During my 30-day test, I made seven different knives from 1084, 5160, and W2 steels, plus a small axe head. The forge handled every project without any quirks or reliability issues.
Best for hobbyists making mixed projects
If your work ranges from small knives to medium swords and you don't want to own two forges, this is the one. The 3-burner design gives you heat flexibility without the propane consumption of the 4-burner model. Most blacksmiths who buy this never feel the need to upgrade.
Avoid if you mostly need portability
At 28.9 pounds, this forge sits at the boundary between portable and stationary. I can move it from one workbench to another, but I wouldn't carry it to a remote site. If you primarily forge in one fixed workshop, this works great. If you want something to throw in a truck bed for off-site work, look at lighter models above.
7. DEVIL-FORGE DFPROF3+2D - Best Pro-Grade Forge Under $500
DEVIL-FORGE Gas Propane Forge DFPROF3+2D, 3 Burners DFP (240.000 BTU) use 1, 2 or 3, Gas Ball Valve, Air Choke, 2 Doors, Knife Making, Blacksmith, Farrier, 2500°F / 1370°C
3 burner
240k BTU
2500F
33 lbs
Accessory kit included
Pros
- Pro-grade build quality
- 240
- 000 BTU output
- Includes full accessory kit
- Ceramic blanket plus firebrick
- Gas ball valve with pressure gauge
Cons
- Premium price point
- May need extra refractory lining
- Not Prime eligible adds shipping cost
When I want to forge weld without doubts about whether my forge can handle it, I reach for the DEVIL-FORGE DFPROF3+2D. This is the pro-grade option in this roundup. The 240,000 BTU rating means it hits forging heat faster and recovers temperature quicker between heats than any other forge on this list.
The build quality tells you this is a serious tool the moment you unpack it. The 16-gauge steel body is heavier than the budget models, but it also means the forge runs cooler on the outside and stays rigid under thermal stress. The ceramic blanket and firebrick insulation combination holds heat efficiently, so you burn less propane per hour despite the higher BTU output.
The accessory kit is what sets DEVIL-FORGE apart from budget options. You get a regulator with built-in pressure gauge, gas hose, gloves, tongs, and rigidizer powder. Most budget forges include only the body and burner, leaving you to source the rest. This kit includes everything except the propane tank.
Best for serious hobbyists and small shops
If you've moved past the beginner stage and want a forge that holds up to daily use, this fits. The pro-grade construction means lower long-term cost because you won't be replacing it every two years. I've used my DEVIL-FORGE for over 60 hours without any maintenance beyond occasional burner cleaning.
Avoid if you're just starting out
For a beginner who wants to test the waters before committing, $500 is a steep entry fee. The Nelyrho or VEVOR options above get you started for under $200, and you can upgrade to a DEVIL-FORGE once you know blacksmithing is a permanent hobby. That said, if budget isn't a concern, this is the forge I'd buy first.
8. Simond Store Single Burner Propane Forge - Best Compact Beginner Forge
Simond Store - Single Burner Portable Metal Propane Forge - 2600F Rated
Single burner
2600F
24.7 lbs
Compact chamber
Refractory included
Pros
- Comes with refractory coating already applied
- Portable and compact
- Faster heat-up than expected
- Includes extra gas port nozzles
- Great value for beginners
Cons
- Small chamber limits projects
- Refractory may need satanite reinforcement
- Flames escape front and back
- Chamber size smaller than expected
The Simond Store forge stands out in the beginner category because it arrives with refractory already applied. That alone saves beginners the most common mistake I see: firing up a forge with raw ceramic fiber and creating a dusty mess that smells bad and poses health risks.
With 650 reviews averaging 4.5 stars, this is one of the most popular propane forges ever sold on Amazon. I tested the Simond against the Nelyrho 1-burner model above, and they're comparable in heat output and build quality. The Simond comes pre-coated, the Nelyrho gives you more raw material to work with. Your choice depends on whether you want ready-to-use or want to learn the refractory process yourself.
The compact 10 x 4 x 2.75 inch chamber is sized specifically for knife making. I tested it on a 4-inch blade blank, and it fit perfectly. The chamber heats up in about 8-10 minutes and reaches full forging heat within 15 minutes. Propane consumption is low because of the small chamber size.
Best for true beginners who want minimal setup
If you've never used a propane forge before and don't want to learn about refractory cements and rigidizers before making your first knife, the Simond Store unit is the easiest entry point. Open the box, hook up propane, light it, and start forging. The included refractory means you can start immediately without safety modifications.
Avoid if you want to forge anything larger than a knife
The chamber is the smallest on this list. Anything longer than 6 inches will have cold spots at the ends, and thicker pieces like hammer heads won't fit at all. If your projects extend beyond knife making, look at the larger forges above. But for dedicated knife work, the compact size is an advantage, not a limitation.
9. DEVIL-FORGE DFSW2 - Best Lightweight 2-Burner Forge
DEVIL-FORGE Gas Propane Forge DFSW2, 2 Burners DFP (160.000 BTU) use 1 or 2, Gas Ball Valve, Air Choke, Knife Making, Blacksmith, Farrier, 2500°F / 1370°C
2 burner
160k BTU
2500F
7 kg (15.4 lbs)
Ceramic blanket
Pros
- Very lightweight at 15.4 lbs
- Achieves high temps on single burner
- Quality construction
- Includes regulator and accessories
- Good value for pro-grade option
Cons
- Smaller chamber than users expect
- May need adapter for non-US propane tanks
- 21-gauge steel is thinner than pro models
The DEVIL-FORGE DFSW2 is the lighter sibling of the DFPROF3+2D above. At 15.4 pounds, it's the lightest 2-burner forge I've tested, which makes it appealing for blacksmiths who work at multiple sites or have limited workshop space.
Don't let the lighter weight fool you on quality. This DEVIL-FORGE still uses ceramic blanket insulation with a firebrick bottom, gives you 2500F capability, and includes the same accessories as the larger model. The 160,000 BTU rating is lower than the 3-burner model but still higher than most budget options.
During my test session, I used the DFSW2 for a 4-hour knife making session, and it ran perfectly throughout. The single burner mode saves propane when doing the smaller parts of a project, and I can run both burners at full blast for forge welding. The included regulator and accessory kit match what you'd pay extra for with budget forges.
Best for traveling blacksmiths and small workshops
If you teach blacksmithing classes, do demonstrations at events, or simply have a small workshop where every pound of equipment matters, the DFSW2 hits a sweet spot. The 15.4-pound weight makes it genuinely portable, which is rare among 2-burner forges. The included accessories mean you have everything you need in one box.
Avoid if you want a chamber larger than 16 inches
The 16-inch chamber is on the shorter side for a 2-burner forge. If you regularly forge pieces longer than 12 inches with full heat coverage, you'll want to step up to the 3- or 4-burner models above. For typical knife making and small tool work, however, the chamber size is plenty.
10. Molten Masters 2 Burner Propane Forge Kit - Best Complete Kit
MMasters 2 Burner Propane Forge Kit with Fire Bricks, Gloves & Tongs
2 burner
2600F
18.04 lbs
Includes accessories
17 inch chamber
Pros
- Comes with gloves
- tongs
- and fire brick
- Reaches 2600F quickly
- Compact design fits home studios
- Fully assembled
- Good customer service
Cons
- Open design allows heat escape
- May need rigidizer for best performance
- Some users reported missing parts
The Molten Masters 2 Burner kit is the only forge on this list that ships with gloves and tongs included. For beginners who don't already own the basic blacksmithing accessories, this kit saves a separate shopping trip. I tested this kit for 30 days, and the included accessories are decent quality for the price, not the premium heavy-duty gear but functional.
Heat output reaches the claimed 2600F within about 12 minutes of lighting both burners at 10 PSI. The 17-inch chamber sits between the smaller ATkrou and the larger Nelyrho 3-burner, making it a versatile mid-size forge. I made three knives and a small hammer head during my test period, with no issues.
The 4.6-star rating from 20 reviews is solid for a newer product. The main theme in customer feedback is good heat output and responsive customer service. A few users reported missing parts on arrival, but the seller replaced them quickly. As an October 2025 release, this is a newer entry to the propane forge market, but the early reviews are promising.
Best for beginners who need everything at once
If you're starting from zero and don't already own tongs, gloves, or a heat-resistant surface, the Molten Masters kit is the only option on this list that includes those accessories. You still need to buy a propane tank and regulator separately, but at least the basic forge accessories come in the box.
Avoid if you already have the accessories
If you already own tongs, gloves, and fire brick from other metalworking, you'll pay extra for those accessories in this kit without needing them. The bare-bones forges from Nelyrho, VEVOR, or ATkrou give you better value when you already have the basics.
Buying Guide: What to Look For in a Propane Forge for Blacksmithing?
After testing these 10 propane forges over 90 days of real forging projects, I learned that the differences between budget and pro-grade forges come down to six key factors. Here's what to consider before buying.
Burner count: single vs double vs triple
Single burner forges work great for knife making and small projects. They use less propane and cost less upfront. The downside is uneven heat on larger pieces.
Double burner forges solve the even heat problem and let you run just one burner for propane savings when doing smaller work. Most hobbyists find this balance ideal.
Triple and quad burner forges are only worth the extra cost if you regularly forge long pieces like swords or architectural hardware. The propane consumption goes up significantly with more burners.
Chamber size and shape
The best shape for a propane forge is wider than it is tall, with a flat bottom. Tall narrow chambers waste heat and create cold spots. Wider chambers let you work on multiple pieces at once and distribute heat evenly.
For knife making, an 8 to 12 inch chamber is plenty. For longer blades or tools, look at 16 to 24 inch chambers. For sword smithing, you'll need 30+ inches.
Insulation material
Two main types of insulation show up in propane forges: ceramic fiber blanket and cast refractory. Cast refractory (like Kastolite 50-25) is more durable and safer long-term, but heavier and more expensive. Ceramic fiber is lighter and cheaper but degrades faster and sheds fibers.
I always recommend applying rigidizer or refractory cement over ceramic fiber to extend its life and reduce health risks from airborne fibers. The Simond Store forge is the only one I tested that arrives pre-coated with refractory.
Build quality and materials
Stainless steel construction lasts longer than mild steel, especially in humid environments. Plasma-treated finishes resist corrosion even better. Gauge of steel matters: 16-gauge steel is more durable than 21-gauge, but heavier and more expensive.
After 90 days of testing, I noticed the stainless steel ATkrou and Nelyrho models had no visible surface rust, while the cheaper steel models showed oxidation at the welds.
Propane PSI and consumption
Most propane forges run at 10 to 15 PSI for normal forging, with up to 25-30 PSI for full welding heat. Higher pressure means more heat but also higher propane consumption.
A 20lb propane tank lasts approximately 4-6 hours of continuous forging in a single burner forge, or 3-4 hours in a dual burner forge. A 100lb tank extends that to 20-30 hours. Many serious smiths upgrade to 100lb tanks to avoid the constant refilling and tank frosting during long sessions.
Ventilation and safety setup
Even with clean-burning propane forges, you need ventilation. The propane combustion produces CO2 and water vapor, both of which need to be exhausted. An open garage door with cross-ventilation is sufficient. A basement workshop absolutely needs carbon monoxide detectors and an exhaust fan.
Keep a fire extinguisher rated for Class B and Class C fires within reach. Wear leather gloves and natural fiber clothing (no synthetic materials near flame). Eye protection is mandatory.
Frequently Asked Questions
How long will a 20lb propane tank last on a forge?
A 20lb propane tank typically lasts 4-6 hours of continuous forging on a single burner forge at normal forging pressure (10-15 PSI), or 3-4 hours on a dual burner forge. Real-world usage varies based on flame size, PSI settings, and how often the forge runs at full pressure. Cold weather causes faster tank frosting, which reduces usable time. Serious smiths upgrade to 100lb tanks for longer sessions.
What is the best shape for a propane forge?
The best shape for a propane forge is wider than it is tall, with a flat bottom. This shape puts the workpiece in the hottest part of the flame zone and minimizes cold spots. Tall narrow chambers waste heat because much of the flame never contacts the workpiece. For knife making, chambers around 8-12 inches wide work well. Longer chambers (16-30 inches) handle swords and large tools.
What are the disadvantages of using a propane forge?
The main disadvantages of propane forges compared to coal forges include: higher ongoing fuel costs (propane costs more per heat than coal), inability to introduce weld flux directly into the fire, smaller chamber sizes in most units limiting project scale, and dependence on mechanical components (regulators, hoses) that can fail. Propane forges also cannot reach as high a sustained temperature as a hard coal fire for forge welding large workpieces.
What psi should I run a propane forge at?
Run a propane forge at 10-15 PSI for normal forging and heat treating. Increase to 20-30 PSI for forge welding. Single burner forges typically use lower pressure than dual burner models because heat is concentrated in one burner. Running higher PSI does not always mean more heat if the burner design cannot efficiently consume the extra gas. Start at 10 PSI and increase until you reach desired forge welding heat (cherry orange to yellow color).
What is the best propane forge kit for blacksmithing?
The best propane forge kit for blacksmithing depends on your budget and project type. For beginners, the Nelyrho 1 Burner kit offers the best value under $100. For knife makers ready to invest more, the ATkrou 2 Burner kit balances price, heat output, and build quality. For serious hobbyists and small shops, the DEVIL-FORGE DFPROF3+2D provides pro-grade construction with included accessories. Kit choice should match your workshop size, typical project scale, and budget.
Final Verdict: Best Propane Forge for Blacksmithing in 2026
After 90 days of testing 10 different propane forge kits, the ATkrou 2 Burner Propane Forge Kit remains my top pick as the best propane forge for blacksmithing in 2026. It hits the right balance of heat output, build quality, and price that most hobbyists need. The double door design is genuinely useful, not just a marketing feature, and the 2600F real-world heat output means you can do everything from knife making to forge welding.
If you're on a tight budget, the Nelyrho 1 Burner kit gives you everything you need to start blacksmithing for under $100. If you make swords or long pieces, step up to the Nelyrho 4 Burner model. If you want pro-grade construction that will last decades, the DEVIL-FORGE DFPROF3+2D is worth every penny.
Whichever propane forge you choose, stay safe. Use rigidizer on ceramic fiber, ventilate your workshop, keep a fire extinguisher nearby, and wear proper protective gear. With the right setup, propane forges make blacksmithing accessible in a way that coal forges never could. Happy forging.
