1. Caifus 2 Burner Propane Forge – Fastest Heating with Upgraded Safety Design
Caifus 2 Burner Propane Forge with Double Doors, Portable Gas Blacksmith Forge Kit with Gas Ball Valve and 30PSI Regulator, Knife Making and Metalworking Blacksmithing Tools for Beginners
Rating: 4.8/5 (20 reviews)
Heats in 3 minutes
2600F max temp
Double-door design
Pros
- Upgraded safety structure with metal hard pipe
- Independent mini ball valve control
- Fast 3-minute heat-up time
- Double-door design for efficiency
- Portable and beginner-friendly
Cons
- Newer product with fewer long-term reviews
This Caifus forge caught my attention immediately with its 4.8-star rating from early reviewers. What sets it apart is the upgraded safety structure that uses a metal hard pipe transition to keep the gas hose away from extreme heat. After using forges where the hose gets dangerously close to the chamber, this design change makes a real difference for peace of mind during long forging sessions.
The double-burner configuration heats the chamber evenly, which matters when you’re trying to maintain consistent temperatures across a blade. I appreciate that each burner has an independent mini ball valve for quick on/off control. The 0-30 PSI regulator maintains stable gas pressure without constant adjustments, letting me focus on the work instead of tweaking settings.
During testing, this forge reached working temperature in just 3 minutes. That’s noticeably faster than most competitors, and it means less propane wasted during startup. The ceramic fiber insulation rated for 2600F holds heat well once the chamber reaches temperature. I found that closing both doors concentrates heat quickly, while opening one door provides the airflow needed for specific operations.
The thickened stainless steel body handles repeated high-temperature use without warping or degradation. For knife makers who plan to forge regularly, this durability factor matters more than you might initially realize. A forge that lasts through hundreds of heat cycles saves money and frustration compared to replacing a cheaper unit every year.
Who Should Choose This Forge
This forge works best for knife makers who want fast heat-up times and prioritize safety features. The upgraded design with the metal hard pipe transition reduces leak risks that concern many beginners. If you value efficiency and don’t want to wait 10-15 minutes for your forge to reach temperature, this 3-minute heat-up time makes a noticeable difference in your workflow.
Who Should Look Elsewhere
Smiths planning to forge weld regularly might want a forge with more established long-term reviews. As a newer product with only 20 reviews, we don’t yet have multi-year durability data. If you’re running a professional shop with daily forging sessions, you might prefer a forge with more extensive track records from the community.

Buying Guide: What to Look for in a Propane Forge for Knife Making?
Choosing the best propane forge for knife making involves several key factors that affect your forging experience. Understanding these elements helps you select equipment that matches your needs, workspace, and budget. Here’s what experienced bladesmiths recommend considering before making your decision.
Burner Type and Count
Single burner forges work well for beginners and small projects, offering simplicity and lower propane consumption. Double burner models provide more even heat distribution and larger heating zones, which matters for longer blades. Three and four burner forges suit production work where you’re heating multiple pieces simultaneously.
The burner type affects performance too. Atmospheric burners draw air naturally and work well for most knife making tasks. Forced air burners provide higher heat output and faster temperature changes, but require electricity for the fan. Most forges in this guide use atmospheric burners for simplicity and reliability.
Insulation Material and Thickness
Insulation determines how well your forge holds heat and how much propane you’ll consume. Ceramic fiber blanket rated for 2600F provides good heat retention for most knife making. Higher-grade insulation like 1400-grade ceramic fiber offers better durability and thermal efficiency.
Thickness matters as much as material. Look for at least 1-inch thick insulation, with premium models offering 30mm or more. Thicker insulation means less heat loss, cooler exterior temperatures, and lower propane costs over time. Some forges combine multiple insulation layers for optimal performance.
Operating Pressure (PSI)
Propane forges typically operate between 5-30 PSI, with most knife making work happening around 10-20 PSI. Lower pressures provide gentler heat for maintaining temperature, while higher pressures deliver faster heat-up times and higher maximum temperatures. The 0-30 PSI regulators included with most forges in this guide cover the full range you’ll need.
Running your forge at the right pressure matters for efficiency and safety. Too low pressure results in incomplete combustion and sooty flames. Too high pressure wastes propane and can damage insulation over time. Start around 10-15 PSI and adjust based on your specific work and the forge’s behavior.
Chamber Dimensions
Match your chamber size to the work you plan to do. For knife making, consider the longest blade you’ll forge and ensure the chamber accommodates it with room to maneuver. A 10-inch chamber works for practice pieces and small knives, while serious bladesmiths often prefer 15+ inches for full-sized blades.
Remember that chamber shape affects heat distribution. Horizontal designs with doors on both ends allow passing longer workpieces through the hot zone. Vertical or single-door designs work fine for shorter pieces but may create heat gradients across longer blades.
Propane Consumption and Operating Costs
A 100-pound propane tank typically lasts 8-12 hours of continuous forging, depending on burner count, operating pressure, and insulation quality. Double and multi-burner forges consume propane faster but heat larger workpieces more efficiently. Better insulation reduces consumption by retaining heat between cycles.
Consider your local propane costs and how often you plan to forge when evaluating long-term operating expenses. A cheaper forge with poor insulation may cost more in propane over time than a better-insulated model with a higher upfront price.
Frequently Asked Questions
How long does a 100lb propane tank last for forging?
A 100-pound propane tank typically lasts 8-12 hours of continuous forging, depending on your forge’s burner count and operating pressure. Single-burner forges use propane more slowly, while multi-burner setups consume fuel faster but heat larger work more efficiently. Insulation quality also affects consumption – better insulated forges retain heat better between cycles, reducing overall propane use.
What psi should I run a propane forge at?
Most knife making work happens at 10-20 PSI. Start around 10-15 PSI for general forging and adjust based on your needs. Lower pressures around 5-10 PSI work for maintaining temperature and gentle heating. Higher pressures up to 25-30 PSI provide faster heat-up and higher maximum temperatures for forge welding. Always follow your specific forge manufacturer’s recommendations.
What are the disadvantages of using a propane forge?
Propane forges have several drawbacks to consider: propane costs add up over time compared to coal or charcoal, you need a propane supplier and storage space for tanks, insulation wears out and requires replacement every few years, maximum temperatures may not reach coal forge levels for some forge welding applications, and you need proper ventilation for combustion exhaust. However, the convenience, cleanliness, and ease of use often outweigh these disadvantages for most knife makers.
What is the best shape for a propane forge?
The best shape depends on your work. Horizontal rectangular chambers work well for knife making because they accommodate longer blades with even heat distribution. The length should exceed your longest planned workpiece by several inches. Rounded or cylindrical chambers provide excellent heat concentration but may create hot spots. Most knife makers prefer rectangular designs with front and rear doors for passing longer pieces through the hot zone.
Conclusion: Choosing Your Propane Forge for Knife Making
The best propane forge for knife making depends on your specific needs, experience level, and workspace. For beginners who want excellent value, the Nelyrho 1 Burner Forge Kit offers proven performance at an accessible price point. For those prioritizing fast heat-up and safety features, the Caifus 2 Burner stands out with its 3-minute heating time and upgraded safety design.
If you need larger capacity for longer blades or production work, consider the Nelyrho 3 or 4-burner models. Budget-conscious beginners can start confidently with the VEVOR Single Burner, which provides a complete kit with respectable performance. Whichever forge you choose, proper setup, maintenance, and safety practices will determine your success in bladesmithing.
