Best Forges for Knife Making (August 2026) In-Depth Reviews
The best forges for knife making give you controllable, even heat for shaping steel without asking you to build a permanent shop around them. Every forge in this guide is a propane model, and the useful differences are burner count, stated maximum temperature, insulation, chamber length, door design, and the accessories included.
A knife-making forge is a refractory-lined heating chamber that brings steel to a workable heat before it goes to the anvil. For a first forge, I would put reliable heat control, protected gas routing, and a chamber that matches the stock you plan to forge ahead of headline heat claims.
The ten selections below come from supplied product listings, specifications, ratings, and review counts rather than an invented hands-on test. Blacksmithing communities repeatedly flag uneven heat, excess airflow, unprotected ceramic wool, and poor ventilation as problems that can make a first session frustrating or unsafe.
Forging is only one stage of a sound blade. Once the profile is forged and normalized, our guide to heat treating ovens for knife making is a useful next read for makers who want repeatable thermal cycles.
Top 3 Picks for 2026
The Caifus is the editor’s choice for its two burners, double doors, and hard-pipe transition that keeps the hose farther from the hot body. The VEVOR two-burner model is the straightforward ready-to-use choice, while SIMOND makes sense when a stated 10-inch-long internal chamber and compact format are more useful than a wider setup.
These ten propane forges make the August 2026 quick overview
Use the comparison below to narrow the field by burner count and the published feature that most affects knife work. A stated temperature is a capability figure, not a promise that every point in a chamber reaches that number at the same setting.

1. Caifus 2 Burner Forge is the safety-focused all-round choice
- Hard-pipe hose transition
- Two burners
- Double doors
- 0-30 PSI regulator
- No chamber dimensions listed
- Low review count
2 burners
2600F insulation
Double doors
Caifus lists a two-burner propane forge with double doors, a 0–30 PSI regulator, and a separate mini ball valve. Its defining detail is a metal hard-pipe transition between the hot forge area and the gas hose, intended to keep the hose away from extreme heat.
That layout answers a concern that appears often in community discussions: residual heat can damage a hose when it sits too close to the forge body. The stainless-steel body and stated 2,600°F ceramic-fiber-insulation rating make this a strong specification match for knife blanks and general metalwork.
The double doors let you close the chamber around shorter work, which the listing says heats metal faster and reduces propane use. For long or prolonged high-heat work, the manufacturer advises opening one door to manage airflow and avoid overheating.
I would regard the published three-minute heat-up statement as a warm-up claim to verify in your own ventilated setup, since tank level, regulator setting, and ambient conditions change results. Chamber dimensions are not supplied, so makers working long billets should confirm usable interior length before choosing it.
This forge fits makers who put gas-hose routing first
Choose this Caifus model when you want two burners but also want an explicit design response to hose heat exposure. It is a sensible match for a beginner who will work through a safety checklist before every lighting cycle.
This forge needs a size check for long blades
Skip assumptions about blade capacity because the listing does not state internal measurements. Measure your most common stock length, allow room for tongs and movement, then compare that requirement with the seller’s current details.
2. Nelyrho 1 Burner Forge is the simple compact starter
- Single-burner simplicity
- 0-30 PSI range
- Stainless-steel build
- Standard tank connection
- Refractory coating recommended
- No chamber dimensions listed
1 burner
2600F stated heat
1 inch insulation
The Nelyrho one-burner forge has a stainless-steel build, a 0–30 PSI burner-nozzle pressure range, and a stated 2,600°F maximum. Its hose connection is described as compatible with standard propane tanks, so the basic fuel connection is familiar to many home-shop users.
A single burner is not automatically inadequate for knife work. It can be a more focused choice for small blades and short pieces, provided the chamber is heated evenly and you move the steel rather than leaving one area in the hottest zone.
The listing specifies one-inch insulation and recommends applying refractory material or rigidizer to the fire-resistant insulation. That recommendation should be treated as a setup task because exposed ceramic fiber is one of the material concerns makers regularly raise.
After a session, Nelyrho specifically advises disconnecting hoses or burners to keep residual heat from melting the hose. A cool-down routine should include shutting off fuel, allowing the forge to cool, and keeping hands away from fittings until they are safe to handle.
This forge suits first projects and short knife blanks
This is the best beginner forge for knife making when one burner, a basic propane connection, and a stainless body are the right level of complexity. Its 308 supplied reviews give it a broader review base than several newer two-burner entries here.
This forge calls for a coated-insulation setup
Do not select it if you want a listing that states completed refractory protection. Plan for rigidizer or refractory material, appropriate respiratory protection while handling insulation, and a review of the current assembly instructions.
3. Nelyrho 2 Burner Forge is the longer-stock alternative
- Two burners
- Stainless-steel build
- 0-30 PSI range
- Standard tank connection
- Refractory coating recommended
- No chamber dimensions listed
2 burners
2600F stated heat
1 inch insulation
Nelyrho’s two-burner version keeps the same published 2,600°F rating, stainless-steel construction, one-inch insulation, and standard propane-tank compatibility as the single-burner model. The material change is the second burner, which gives a longer heated zone in a typical forge layout.
For a knife maker, that extra heat source can be useful when heating more of a blade blank at once or working longer bar stock. It does not remove the need to watch color and rotation, because two burners still need balanced adjustment to avoid a localized hot spot.
The listing again recommends rigidizer or refractory material over the insulation. It also repeats the warning to disconnect the hose or burner after heating, so the same deliberate shutdown practice applies here.
Compared with the one-burner Nelyrho, this is the more logical gas forge for bladesmithing when your work is moving beyond very small projects. The listing does not provide internal chamber dimensions, which limits how confidently anyone can match it to a particular blade length.
This forge helps when a single heated zone feels limiting
Pick this version when you expect to make longer knives, heat more stock at a time, or want a second burner available for more demanding work. Start both burners conservatively and learn the chamber’s heat pattern before attempting a finished blade.
This forge still requires insulation preparation
The larger burner count does not change the listing’s rigidizer or refractory recommendation. Makers who do not want to prepare and protect ceramic fiber should choose only after confirming the supplied kit’s current lining condition.
4. SIMOND Single Burner Forge is the compact chamber pick
- Listed chamber dimensions
- Portable format
- 2600F rating
- 649 reviews
- Single burner
- Very narrow 2.75 inch chamber height
1 burner
2600F rated
2.75 x 4 x 10 inch chamber
SIMOND gives the clearest internal-size statement in this roundup: 2.75 inches high, 4 inches wide, and 10 inches long. That makes it much easier to decide whether your usual knife blank and tong position will fit before it arrives.
It is a single-burner portable propane forge rated to 2,600°F. The compact form is practical for a small workspace, although the 2.75-inch internal height is a real physical limit when you are using thick stock, tall tongs, or bulky fixtures.
The listing calls it suitable for knife making and heat treatment, and the supplied review count of 649 is the largest among these ten products. Reviews do not replace safe setup, but that larger sample is a helpful comparison point when feature lists of compact forges look similar.
For a small forge for knife making, published internal dimensions beat a vague capacity claim. Measure the full working envelope rather than the blade alone; the stock needs clearance to enter, turn, and leave without scraping the lining.
This forge works best for compact knife projects
Choose SIMOND for short blade blanks and a shop where a portable 10-inch chamber is a more realistic fit than a large dual-burner unit. Its stated internal measurements make project planning unusually straightforward.
This forge limits tall or wide workpieces
The narrow chamber height makes this a poor match for stock that needs much vertical room or for users who want a large firebrick-supported work area. Check the 4-inch width and 2.75-inch height against your tongs and steel, not just your finished knife dimensions.
5. ATkrou 2 Burner Forge is the close-burner double-door option
- Close-spaced burner design
- Double doors
- 1400-grade ceramic fiber
- Plasma-treated steel
- Protective coating recommended
- No chamber dimensions listed
2 burners
2600F insulation
Double doors
The ATkrou two-burner forge is built around a claim that its upgraded burners sit to stack heating energy rather than leaving a poorly heated gap. That design aim directly addresses the uneven-heat complaint common in blade-forging discussions, especially when a maker is heating longer bar stock.
It has double doors, a plasma-surface-treated stainless-steel construction, and a 1,400-grade ceramic-fiber blanket rated up to 2,600°F. Closing both doors is described as a way to heat steel faster and reduce propane use.
The manufacturer recommends refractory cement and a ceramic-fiber cover for protection and stable use. Read that as an instruction to plan lining treatment, because a high stated insulation temperature does not mean the exposed surface should be left as received.
The product has 502 supplied reviews, a useful volume for a two-burner portable forge. Burner spacing is only one part of even heat: regulator setting, air intake, preheat time, stock location, and your own observation all affect the result.
This forge answers the need for a more even dual-burner zone
ATkrou is worth shortlisting when you want two burners specifically to heat longer pieces and its close-burner design appeals to you. Make a few practice heats with mild steel first to learn where the chamber runs hottest.
This forge requires a lining-protection plan
Do not ignore the listed recommendation for refractory cement and a protective layer. Insulation condition affects heat retention and safe cleanup, so inspect it during assembly and after every session.
6. DEVIL-FORGE DFSW2 is the specified 16-inch chamber package
- 16 inch chamber
- Firebrick floor
- Air chokes
- Included tongs and gloves
- 2500F stated maximum
- 16-pound unit needs stable support
2 burners
2500F
6 x 4.8 x 16 inch interior
The DEVIL-FORGE DFSW2 supplies a detailed working-space picture: a 6-by-4.8-by-16-inch interior, reduced to 3.2 inches in height when the ceramic firebrick is in place. That 16-inch depth is a meaningful advantage for knife makers who want a documented longer chamber.
Its two DFP burners, gas ball valve, and air chokes can be used as one or two burners according to the listing. The listed maximum temperature is 2,500°F, and the package includes a regulator with gauge, hose, clamps, firebrick, tongs, gloves, rigidizer powder, brush, and manual.
For lining, the interior uses one inch of ceramic blanket and a 20 mm firebrick bottom. The firebrick adds a durable base and changes the available internal height, so use the stated 3.2-inch installed height when deciding whether a fixture or thick billet will fit.
At 16 pounds, it is still moveable, but it deserves a stable noncombustible stand rather than a casual tabletop position. The inclusion of basic accessories helps first-time makers begin the setup, yet safe gloves and tongs never replace ventilation, eye protection, and controlled fuel handling.
This forge gives longer-blade makers a measurable chamber
Pick the DFSW2 if a published 16-inch interior is more persuasive than a generic large-capacity label. It suits users who want to compare actual working dimensions before choosing a dual-burner forge.
This forge needs allowance for the firebrick floor
The installed firebrick lowers interior height from 4.8 inches to 3.2 inches. Use that smaller figure when checking clearance for tongs, blade thickness, and any support you expect to use.
7. Molten Masters 2 Burner Forge is the accessory-inclusive compact kit
- Two burners
- Gloves and tongs included
- Firebrick included
- 18.04-pound listed weight
- Low review count
- Protective coating recommended
2 burners
2600F stated heat
Gloves tongs and firebrick
Molten Masters lists a 2,600°F dual-burner propane forge aimed at hobbyists and casual users. It includes heat-resistant gloves, insulated tongs, and a firebrick, which creates a more complete starting kit than a bare forge body.
The published item weight is 18.04 pounds, and the package dimensions are 17.04 by 8.54 by 7.99 inches. Those measurements describe the shipped package, not the internal chamber, so they cannot be used as a blade-capacity specification.
Like several entries here, its listing recommends applying rigidizer or another protective coating to the ceramic-fiber blanket. It also says to disconnect the hose after use so residual heat does not transfer toward the hose.
I would treat the gloves and tongs as useful included items, not proof that the forge is ready for every job out of the box. Confirm the tongs grip your stock safely, use suitable protective clothing, and set up on a noncombustible surface in an open, ventilated work area.
This forge provides a convenient starting accessory set
Choose Molten Masters when you want a dual-burner kit that arrives with basic handling accessories and firebrick. It is an approachable option for someone building a first set of blacksmithing tools in stages.
This forge has less review history than established listings
The supplied review count is 18, far below several alternatives in this guide. Read current reviews and documentation closely, inspect all gas connections, and protect the insulation before relying on it for a finished blade.
8. VEVOR 2 Burner Forge is the ready-to-use dual-burner choice
- Pre-installed accessories
- Two selectable burners
- Two insulation layers
- 373 reviews
- No internal chamber dimensions listed
- Heavier 10.4-kilogram unit
2 burners
2600F
30 mm wool and 30 mm brick
VEVOR’s portable two-burner forge states a 2,600°F maximum and says forging can begin after a three-minute preheat. Its key convenience claim is that the main accessories arrive pre-installed, so setup after connecting to a propane tank is more direct.
The listing says you can select the number of burners, which is useful when the piece does not need both burners. That flexibility can help a maker avoid running a larger heated area than the job requires, although correct adjustment still matters more than burner count alone.
Its insulation stack combines 30 mm thermal-insulation cotton and 30 mm thermal-insulation brick. The body uses cold-rolled plate, the burner uses 45# steel, and the listed unit weight is 10.4 kilograms.
VEVOR gives exterior dimensions of 15.7 by 8.5 by 7.5 inches but does not state internal chamber dimensions in the supplied information. Do not treat the exterior measurement as working capacity; ask for the interior size when long knives are central to your plan.
This forge makes initial setup less involved
Choose this VEVOR if pre-installed key accessories and the option to operate one or two burners match your approach. Its 373 supplied reviews offer a substantial body of buyer feedback to examine alongside the product details.
This forge needs an interior-capacity confirmation
The external measurements are useful for allocating stand space, not for determining blade length. Confirm the chamber before selecting it for long stock, forge-welding attempts, or projects needing a broad even-heat zone.
9. VEVOR Single Burner Forge is the multilayer-insulated small-shop option
- Three insulation layers
- Pre-installed accessories
- Carry handle
- 15.6-pound weight
- Single burner
- No internal chamber dimensions listed
1 burner
2600F
Cotton brick and refractory cement
The single-burner VEVOR is a compact propane forge with a stated 2,600°F maximum, pre-installed key accessories, and a carry-handle design. The listing gives exterior dimensions of 13 by 11 by 13 inches and a listed weight of 15.6 pounds.
Its insulation is the standout specification: 30 mm thermal-insulation cotton, 30 mm thermal-insulation brick, and a refractory-cement layer. That three-part description is more complete than listings that state only a blanket, though regular inspection is still sensible after heating cycles and movement.
As a single-burner forge, it is best considered for small knives, short tooling, and controlled practice work. A single burner can keep a compact chamber hot, but it will not create the same extended heating zone that a well-adjusted dual-burner model can offer.
The body is cold-rolled steel, the burner is 45# steel, and the construction is described as weldless. Those are useful build details, but the unlisted internal chamber size remains the open question for a maker planning a specific blade geometry.
This forge fits a portable single-burner workflow
Select this model when multilayer insulation and a carry handle matter more than a second burner. It is a logical candidate for a hobby workspace that can support safe outdoor or purpose-ventilated propane-forge use.
This forge cannot be sized from its exterior dimensions
The product’s stated 13-by-11-by-13-inch measurement does not reveal usable chamber length or clearance. Contact the seller for internal dimensions if your work is larger than a short knife blank.
10. E-cowlboy Dual Burner Forge is the highest stated-heat option
- 2700F stated maximum
- Two 80000-BTU burners
- Air chokes
- Accessory kit included
- Lowest rating in this list
- No chamber dimensions listed
2 burners
2700F stated maximum
Air chokes
E-cowlboy lists a portable dual-burner propane knife forge with a stated 2,700°F maximum, the highest number in this comparison. The listing says each DFP burner is 80,000 BTU and that the operating pressure range is 1–25 PSI.
Air chokes are a meaningful listed control feature because burner air and gas need to be balanced rather than treated as fixed settings. The manufacturer states that different pressure levels need different quantities of air to reach maximum temperature, which is why setup and adjustment matter.
The package includes tongs, firebrick, door handles, a pressure regulator with gauge, a 6.5-foot hose, clamps, brush, and heat-resistant gloves. The steel forge body is described as 16 gauge, or 1.5 mm, and the regulator is listed at 0–0.6 MPa.
Higher stated heat does not turn forge welding into a beginner task. A safe, repeatable knife-making result starts with an even chamber, clean steel, correct heat observation, and a practiced workflow; use the air chokes and regulator gradually instead of chasing a maximum figure immediately.
This forge suits makers who need air-adjustment control
Choose E-cowlboy when two burners, air chokes, and the highest published heat claim are the specifications you want to investigate. It has the hardware for more involved adjustment, which rewards careful setup rather than rushed operation.
This forge needs extra scrutiny of current feedback
Its 4.1 supplied rating is the lowest in this roundup, although it is based on 67 reviews. Read recent buyer feedback, follow the included instructions, and check the full gas path for leaks before every lighting cycle.
The best forge choice comes from burner, heat, insulation, and size
Start with the work, not the forge label. A small hunting knife, a long chef’s knife, a heavy tool, and a forge-welded billet ask for different chamber room and heating-zone length, so write down your typical stock size before comparing listings.
A single burner is enough for short, focused knife work
Single-burner choices such as the Nelyrho, SIMOND, and VEVOR models are simpler to learn and can be appropriate for compact knife projects. Their limitation is not a lack of advertised peak heat; it is the shorter heated area and the need to manage where the steel sits.
A dual-burner forge generally makes more sense once your stock gets longer or you want a broader heated zone. It also introduces two flames to balance, so light practice sessions with scrap steel are a better starting point than a critical blade.
A stated 2300F to 2500F range covers normal forging heat
The research for this guide identifies 2,300°F to 2,500°F as the commonly discussed range for forge welding, while all ten available products list maximum temperatures from 2,500°F to 2,700°F. Steel type, stock size, burner tuning, and where the measurement is taken all change what you see in actual use.
For ordinary knife forging, color and control matter more than chasing the highest advertised number. Overheating can damage steel, and a forge that has one extremely hot spot may be less useful than one that heats the relevant section evenly.
Protected insulation retains heat and reduces avoidable fiber exposure
Ceramic-fiber blanket, firebrick, refractory cement, rigidizer, and thermal-insulation cotton appear throughout the product data. Look for a listing that says what protects the blanket, then follow the maker’s preparation directions before firing the forge.
The Nelyrho, ATkrou, and Molten Masters listings explicitly recommend rigidizer, refractory material, or a protective coating. That matches a frequent forum concern about insulation condition: leave no loose fiber issue unresolved, inspect the lining, and replace damaged materials according to the product guidance.
A measured chamber prevents a frustrating capacity mistake
Only SIMOND and DEVIL-FORGE provide useful interior dimensions in the supplied product data. SIMOND lists a 2.75-by-4-by-10-inch chamber, while DEVIL-FORGE lists a 6-by-4.8-by-16-inch interior and 3.2 inches of height with its firebrick installed.
For other models, exterior dimensions and product photos are not a substitute for a stated interior. Measure your longest likely blank and tongs, then ask for internal length, width, and height before committing to a forge that may be too short.
Propane is the relevant fuel choice for every model here
Every product in this roundup is a propane forge, so propane compatibility is the direct comparison rather than a mixed-fuel contest. The supplied research notes that propane forges are commonly recommended to beginners because their heat is controllable and their setup is contained, but they still need open-air or purpose-built ventilation and disciplined fuel handling.
Natural-gas, electric, and coal setups are separate categories with different installation and workflow demands. If you need tightly programmed thermal cycles after forging, look at our related heat treating ovens for knife making rather than expecting a propane forge to perform an oven’s controlled job.
Ventilation and a shutdown routine are non-negotiable safety steps
Use a propane forge only in a suitable open or purpose-ventilated area on a stable noncombustible support. Keep combustible items clear, wear suitable eye and heat protection, use tools that hold the stock securely, and follow the product manual for lighting and adjustment.
Check hose routing, clamps, regulator, and every gas connection before lighting. After shutting off fuel and allowing a safe cool-down, follow the product-specific hose-disconnection guidance; both Nelyrho and Molten Masters call out residual hose heat in their listings.
High-carbon steel is a common practical starting material
The best material for forging knives depends on the knife design and your heat-treatment knowledge, but high-carbon steel is the usual starting category for a blade meant to harden and hold an edge. Confirm the exact steel’s forging and heat-treatment requirements from a reliable steel-data source before heating it.
Start with one steel type rather than mixing unknown scrap. Consistent stock lets you learn the forge’s heat behavior and your hammer control without adding uncertainty about the alloy.
FAQs
What brand of forge do they use on Forged in Fire?
The research supplied for this guide identifies this as a common search question but does not document one verified, official forge brand for the show. Equipment can vary by production context, so choose a forge from verified chamber, burner, insulation, and safety specifications rather than a television association.
Is knife making a profitable hobby?
Knife making can become a business, but it is not automatically profitable. Forging is only part of the work: materials, time, finishing, heat treatment, tools, safety equipment, and finding customers all affect whether a maker earns more than they spend.
Which is better propane or natural gas forge?
Propane is the more direct answer for this roundup because all ten reviewed products are propane models and their listings describe standard propane-tank connections. Natural gas can suit a dedicated installed setup, but it requires a compatible gas supply and installation plan; choose based on your permitted work area, ventilation, and fuel access.
What is the best material for forging knives?
High-carbon steel is the common practical choice for a forged knife because it can be heat treated for hardness and edge retention. Use a known steel grade with published forging and heat-treatment guidance, rather than unknown scrap, until you can identify and work with its properties safely.
Final Thoughts
For a safety-conscious two-burner start, the Caifus is the standout because of its hard-pipe hose transition, doors, and regulator range. Choose DEVIL-FORGE when a listed 16-inch chamber is the deciding fact, SIMOND for a documented compact interior, or E-cowlboy when air chokes and its higher stated heat claim lead your checklist.
The best forges for knife making are not defined by a single maximum-temperature number. Pick a model with a chamber you can measure, insulation you can protect, burners you can tune, and a workspace where safe propane-forge operation is genuinely possible.
