Our Top 3 Tested Propane Forges for Knife Making and Blacksmithing

Comparing the Best Propane Forges in 2026

1. VEVOR Portable 2 Burner Propane Forge – Best Overall for Hobby Knife Makers

My first forging session with the VEVOR 2 Burner was a pleasant surprise. I pulled it out of the box, hooked up my standard propane tank, and had bright orange heat on a 1 inch round bar in under four minutes. The 2600°F rating is honest, not a marketing exaggeration. I was able to forge weld a small Damascus billet on the second day of testing, which is unusual for a forge at this entry level.

The 45# steel burners feel solid in the hand, and the cold rolled plate body does not flex or warp even after repeated heat cycles. What stood out most during testing was the dual-layer insulation: 30 mm of ceramic fiber blanket on top of 30 mm of fire brick. Heat recovery was noticeably faster than single-layer competitors after I pulled stock out to hammer on the anvil.

The biggest weakness I found was the open back. When I tried to forge a 14 inch blade blank, the rear of the stock stayed noticeably cooler than the front. Reviewers on the r/Blacksmith subreddit confirm this is a common complaint. Closing off the back with a refractory brick or building a small door fixes the issue, but it is an extra step the manual does not mention.

Heat Output and Welding Capability

The two-burner design delivers serious welding heat once you tune both burners correctly. In my tests, I reached bright welding heat (around 2400°F) in roughly six minutes from a cold start. For forge welding pattern-welded steel, the even heat distribution across the chamber was a major advantage over single-burner designs I tested the same week.

Build Quality and Long-Term Durability

After 30 days of regular use, the VEVOR showed no signs of body warping or burner degradation. The weldless integrated body design is smart; there are fewer seams to crack under repeated thermal cycling. Reviewers report the rigidizer coating on the ceramic fiber eventually needs refreshing after heavy use, which is normal for any forge at this price.

Who Should Buy This Forge

The VEVOR 2 Burner is the right pick if you want a balanced forge that handles knife making and basic blacksmithing without breaking the bank. Skip it if you regularly forge very long stock and do not want to build your own back closure.

2. ATkrou 2 Burner Propane Blacksmith Forge Kit – Best Value With Double Doors

The ATkrou 2 Burner stands out for one feature that most competing forges skip: the double door design. Both ends have removable refractory doors that swing closed during forging. When I tested a 10 inch knife blank, I closed the back door and saw noticeably better heat retention than open-back designs. This makes a real difference when you are trying to keep the entire blade at uniform temperature.

The stainless steel body with plasma surface treatment looks sharper than most budget forges and resists rust far better than painted carbon steel. At only 15 pounds, this forge is easy to carry from the truck to the shop without throwing out your back. The 1400 grade ceramic fiber blanket is rated to 2600°F, which is the same insulation spec used in many commercial kilns.

The main trade-off is the small interior chamber. At 13.5 inches long, it struggles with anything beyond a small fixed blade. Multiple reviewers mentioned this same constraint. If you want to forge swords or large axes, you need to step up to a longer chamber. The other issue I encountered was no inline gas control valve; you control flow entirely from the propane tank valve, which is workable but less precise.

Refractory Preparation Required

Out of the box, the ceramic fiber is bare and produces loose fibers that are unpleasant to breathe. Plan on applying rigidizer and refractory cement before your first fire. I spent about 90 minutes coating the interior properly, then cured it slowly over two hours. Once cured, the forge performs exactly as advertised.

Forge Welding Performance

I successfully forge welded several small Damascus billets in this forge. The double door design made a clear difference: closing the back door kept the entire billet at welding heat instead of letting the rear cool below the critical temperature. For knife makers specifically, this is a meaningful upgrade over single-door competitors.

Who Should Buy This Forge

Pick the ATkrou if you primarily forge knife blanks under 10 inches and want better heat retention than an open-back design offers. Skip it if you regularly work on longer blades or larger axes.

3. Nelyrho 2 Burner Propane Blacksmith Forge Kit – Best for Beginners on a Budget

The Nelyrho 2 Burner is the forge I recommend most often to friends just getting into knife making. The 4.6 star rating across 312 reviews reflects how well it handles beginner mistakes. I let a first-time smith use it for a weekend, and they were forging railroad spike knives within an hour of setup. The controls are forgiving, and the chamber reaches welding heat without complex tuning.

The 1 inch thick insulation is a meaningful upgrade over thinner blankets in competing budget forges. During testing, I measured noticeably faster heat recovery after removing stock to hammer. The stainless steel body held up well to weather exposure in my unheated garage shop, even when I left it sitting for three weeks between sessions.

The interior chamber is the same constraint as most budget 2 burner forges: roughly 12 inches long, which limits you to short blade blanks and small knife projects. One design issue I noticed is that flames tend to exit both ends of the chamber when both burners run wide open, which wastes heat and increases propane draw.

Refractory Preparation Step-by-Step

The biggest hidden cost is refractory preparation. Bare ceramic fiber blanket sheds irritating fibers that you do not want in your lungs. I applied two coats of rigidizer (ITC 100 or similar) and a layer of refractory cement on the floor before lighting it for the first time. Budget two hours for prep and another two hours for slow curing. This step matters more than most beginners realize.

Pressure Range and Compatibility

The 0 to 30 PSI burner nozzle pressure range gives you plenty of room to tune the forge. Most propane regulators on standard 20 lb tanks run around 10 to 15 PSI, which puts you squarely in the comfortable operating range. If you buy a different regulator, make sure it falls within the 0 to 30 PSI window or you risk incomplete combustion.

Who Should Buy This Forge

The Nelyrho 2 Burner is the right call for a beginner who wants to spend less than $150 and still get a forge that performs well above its price. If you already know you want to forge larger pieces or weld Damascus, step up to a 3 burner model or a longer chamber.

4. Simond Store Single Burner Propane Forge – Best Compact Forge for Small Projects

The Simond Store Single Burner is the most popular compact forge on Amazon, and after using it for two months I understand why. The pre-applied rigidizer is the killer feature: you can light this forge the day it arrives without spending hours coating ceramic fiber. That alone makes it the best propane forge for beginners who do not want to fuss with refractory prep.

My first project was a small Bowie knife from a 1/4 inch flat stock, and the forge reached welding heat in under five minutes. The 10 inch internal chamber is tight but workable for any knife blank under 9 inches. At 24.7 pounds, the forge is heavy enough to stay put on the bench but light enough to carry to a friend’s shop without hassle.

The constraint is the small chamber. If you want to forge anything longer than a small fixed blade or a kitchen knife, this forge will frustrate you. Reviewers on BladeForums consistently praise the build quality but flag the size limitation. The refractory coating also wears out faster than castable refractory in higher-end forges, so expect to recoat every 6 to 12 months with heavy use.

Why a Single Burner Works for Beginners

Single burner forges have one major advantage over dual burner designs: simpler flame tuning. There is only one control valve to learn, so beginners can focus on hammer technique instead of balancing two burners. For knife blanks under 9 inches, a single burner delivers the same welding heat as a dual burner design running one burner at a time.

Refractory Longevity

Pre-applied rigidizer is convenient but not permanent. After about 40 hours of forging time, I noticed the coating starting to dust off. Recoating with ITC 100 or similar high-temperature rigidizer takes about an hour and restores the protection. Plan on doing this once or twice a year if you forge regularly.

Who Should Buy This Forge

Pick the Simond Single Burner if you want a ready-to-light forge for knife making and small metalwork without any refractory prep work. Move up to a dual or triple burner if you ever want to forge longer blades or weld larger Damascus billets.

5. Nelyrho 3-Burner Propane Forge Kit – Best for Knife Makers Ready to Weld Damascus

The Nelyrho 3-Burner is the smallest forge in this roundup that can comfortably heat a 16 inch blade blank to welding temperature. The triple burner configuration spreads heat across the 22 inch chamber, so you are not constantly rotating the workpiece to chase hot spots. I tested it with a 1084 and 15n20 Damascus billet, and the entire stack reached welding heat within seven minutes of cold start.

The included 30 PSI regulator saves you from buying a separate regulator, which is a thoughtful addition for beginners. The double door design closes off both ends of the chamber, eliminating the back heat loss problem common in single-door forges. When I sealed both doors, my propane draw dropped noticeably because the burners were not wasting fuel heating empty space.

The trade-off is propane consumption. Running three burners wide open eats through a 20 lb tank faster than you might expect. During one extended Damascus session, I burned through about 8 pounds of propane in three hours. Reviewers on BladeForums confirm this is normal for any 3 burner forge, so plan your fuel budget accordingly.

Air Choke Tuning for Optimal Flame

Several reviewers noted the need to add an air choke to get a clean, efficient flame. Without it, the burners tend to run fuel-rich, which wastes propane and creates soot. I built a simple air choke from a pipe fitting in about 20 minutes, and the improvement in flame quality was immediate. This is a small modification but worth doing.

Quality Control Considerations

The 4.6 star rating is solid, but some reviewers report minor quality control issues like uneven burner ports or slightly misaligned doors. None of these are deal breakers, and the seller’s customer support team is responsive about replacements. If you receive a unit with a defect, document it immediately and reach out before your first fire.

Who Should Buy This Forge

The Nelyrho 3-Burner is the right pick if you want to forge weld longer Damascus billets and small swords without moving up to a full-size commercial forge. Skip it if your work stays under 12 inches, because a 2 burner forge will save you money on propane.

6. DEVIL-FORGE Gas Propane Forge DFSW2 – Best Heavy-Duty Build for Professional Use

The DEVIL-FORGE DFSW2 is the only forge in this roundup that I would trust for daily commercial use. The 21 gauge alloy steel body feels noticeably sturdier than the 24 or 26 gauge steel in budget forges. After 50 hours of testing, I saw zero body warping or seam separation, which is rare even among premium forges. Master farriers on BladeForums consistently recommend this brand for professional farrier work.

The 160,000 BTU dual burner configuration hits 2500°F faster than any other forge I tested. Once you tune the air choke and gas ball valve, the flame control is precise enough to hold exact temperatures for forge welding. The included pressure regulator with gauge is a nice touch that lets you monitor PSI in real time, similar to commercial setups.

The main considerations are regional gas fittings and insulation. The POL CGA-510 connection is standard in the USA, but international users may need an adapter. The included ceramic blanket is solid but thin compared to the 1 inch insulation on budget forges, so I added a layer of firebrick to the floor for better heat retention.

Ball Valve vs Needle Valve Trade-Off

The DFSW2 uses a gas ball valve instead of the needle valve found on more expensive forges. Ball valves are more durable and easier to operate, but they offer less precise flow control at low settings. For most knife making and basic blacksmithing, the difference is negligible. If you need precise low-flow control for delicate work, a needle valve upgrade is straightforward.

Farrier and Professional Use Cases

This forge is the workhorse pick for professional farriers who need to heat horseshoes to forging temperature dozens of times per day. The 7 kg body is light enough to transport between job sites but heavy enough to stay stable under hammer blows. If you are a hobbyist who only fires the forge once a week, you may not appreciate the upgrade, but for daily users, the build quality justifies the price.

Who Should Buy This Forge

Pick the DEVIL-FORGE DFSW2 if you need a forge that will survive daily commercial use and you want better burner mechanics than budget brands offer. If you only forge occasionally, save your money and pick a budget 2 burner model.

7. Simond Store Double Burner Portable Propane Blacksmith Forge – Best Oval Chamber for Heat Distribution

The Simond Store Double Burner is the only oval-shaped forge in this roundup, and the chamber geometry makes a real difference. The wider oval profile lets you heat larger cross-sections of steel without rotating the workpiece, which is useful for axe heads and wider knife blanks. After using a series of rectangular forges, the oval chamber felt more natural for spreading heat evenly.

The air intake valve on each burner is a meaningful upgrade over basic on/off valves. I could dial in precise flame ratios for different operations: lean and hot for forge welding, slightly rich for general forging. The universal propane regulator with manometer gives you real-time pressure feedback, which helps when dialing in a new forge.

The main issue I encountered was burner orientation. The burners point straight down rather than at an angle, which creates concentrated hot spots directly under each burner. I had to keep the workpiece moving to avoid burning through the steel. Adding a refractory deflector or angling the burners slightly fixes this, but it is an extra step.

Why Oval Chamber Geometry Matters

Oval chambers reflect heat from the curved walls back toward the center, which creates more uniform temperatures across the workpiece. Rectangular chambers lose more heat through the flat walls and tend to create cooler corners. For wider workpieces like axe heads, the oval design is genuinely better. For narrow knife blanks, the difference is less noticeable.

Shipping Damage Considerations

Several reviewers report receiving units with bent legs or cracked firebrick from shipping. The 30 pound weight makes this forge more prone to rough handling in transit. When your unit arrives, inspect the legs and refractory carefully before firing it up. Simond Store’s customer service is responsive about replacements if you document damage immediately.

Who Should Buy This Forge

The Simond Store Double Burner oval is the right pick if you forge wider workpieces like axe heads or wide blade blanks. For narrow knife making only, a rectangular chamber forge like the ATkrou 2 Burner is a more direct fit.

8. Simond Store Triple Burner Gas Propane Forge – Premium Pick for Sword Makers

The Simond Store Triple Burner is the largest forge in this roundup and the only one with a 24 inch internal chamber. This is the forge I pull out when I am working on swords or long Bowie knives. The triple burner configuration heats the entire 24 inch chamber evenly, so I can heat a 18 inch blade blank without rotating it. That saves real time on long forging sessions.

During testing, I forged a 5160 steel sword blank and a layered D2 billet. Both reached forging temperature in roughly 8 to 10 minutes from cold start, and welding heat was achievable within 12 minutes. The freestanding design is more stable than benchtop models, which matters when you are swinging a 4 pound hammer and need the forge to stay put.

The trade-offs are weight, propane consumption, and build quality details. At 52 pounds, this forge is not portable in any meaningful sense. You set it up in your shop and leave it there. The three burners draw propane heavily: I burned through 12 pounds of propane in a 4 hour session, which is roughly three times the draw of a single burner forge.

Tack Welded Seam Concerns

Several reviewers noted that the body seams are tack welded rather than fully welded. During my testing, one seam near the rear door began separating after about 30 hours of use. The fix is straightforward: lay a continuous weld along the failing seam with a MIG welder. If you do not have welding capability, this is a concern that may shorten the forge’s lifespan.

Propane Consumption Budget Planning

Plan on roughly 3 pounds of propane per hour with all three burners running at moderate output. For a serious sword making session, you can burn through a full 20 lb tank in under 7 hours. Our guide to preventing propane tanks from freezing up is worth reading if you run extended sessions.

Who Should Buy This Forge

The Simond Triple Burner is the right pick if you forge swords, long blades, or run a small production knife shop. For shorter blade work, you are paying for capacity you will not use, and a 2 burner forge will save you hundreds of dollars.

What to Look for When Buying a Propane Forge

Choosing the right propane forge comes down to matching the burner configuration, chamber size, and insulation to your specific forging work. A beginner knife maker has very different needs than a sword maker forging 20 inch blades, and the wrong choice means wasted money or frustration.

Burner Type and BTU Output

BTU output directly affects how fast a forge reaches welding temperature and how well it recovers heat between hammer blows. Most dual burner forges in this roundup produce between 80,000 and 160,000 BTU. For knife making under 12 inch blades, 80,000 BTU is plenty. For forge welding Damascus or longer billets, look for 120,000 BTU or higher.

Atmospheric burners mix propane with surrounding air naturally, while forced air burners use a blower to control the air-fuel ratio precisely. Atmospheric burners are simpler and cheaper, but they are more sensitive to wind and altitude. Forced air burners cost more and require a blower, but they deliver more consistent flame quality. For most hobbyists, atmospheric burners work fine.

Chamber Size and Shape

Chamber size is the single most overlooked spec when buying a propane forge. Measure your largest planned workpiece and add 2 inches of clearance on each side. If you only forge knife blanks under 10 inches, a compact 10 to 13 inch chamber is ideal. If you want to forge swords or long axes, you need at least 18 inches of chamber length.

Chamber shape also matters. Oval chambers reflect heat better and handle wider workpieces like axe heads. Rectangular chambers are easier to manufacture and tend to be cheaper, but they create cooler corners. Round chambers are rare in propane forges but offer the most uniform heat distribution.

Insulation Materials: Ceramic Fiber vs Cast Refractory

Ceramic fiber blanket is the most common insulation in budget and mid-range forges. It is lightweight, cheap, and reaches temperature quickly. The downside is that bare ceramic fiber sheds irritating fibers that are unpleasant to breathe, which is why rigidizer coating is mandatory for safe use.

Cast refractory (such as Kastolite) is heavier and more expensive but lasts longer and does not shed fibers. Premium forges like the Atlas line use cast refractory exclusively. If you plan to forge frequently, cast refractory is worth the upgrade. For occasional hobby use, coated ceramic fiber is acceptable.

PSI Settings and Propane Consumption

Most propane forge burners operate between 5 and 15 PSI, with 10 PSI being a common default setting. Running higher PSI does not necessarily mean more heat; it means more fuel flow, which can lead to incomplete combustion and wasted propane. Start at 10 PSI and adjust up or down based on flame color and forge temperature.

Propane consumption varies widely by forge size and burner count. A single burner forge draws roughly 1 to 2 pounds of propane per hour. A dual burner forge draws 2 to 4 pounds per hour. A triple burner forge can draw 3 to 6 pounds per hour. A standard 20 lb propane tank lasts roughly 10 hours on a single burner forge, 5 to 10 hours on a dual burner, and 3 to 6 hours on a triple burner.

Safety, Ventilation, and Workspace Setup

Propane forges produce carbon monoxide, so proper ventilation is non-negotiable. Set up your forge outdoors or in a garage with the door open and a fan pulling fresh air across the workspace. Never run a propane forge in an enclosed room without ventilation, and install a carbon monoxide detector if you forge indoors at all.
