How to build a simple soup can forge

• You might consider having the flame enter the forge at an angle to ensure the heat spirals around the space and covers the whole inside.
• A coffee can will provide more room, more insulation, and allow for longer length blades.
• Protip: put a magnet on the side of the can. When you think your knife has reached critical, touch the knife to the magnet to check. If it sticks, the knife needs to be heated longer.
