Heat Treatment Furnaces / Knife makers Kiln

The soul of the blade is born in the crucible of the furnace. Once you own your own knife makers furnace, you can begin experimenting with heat treating ideas whenever you desire. Stay up late to heat treat an exciting blade design without having to send it out for heat treating only to receive it back a week later.

Used in the hardening and tempering of knife steel.

Hardening is a way of making the knife steel harder. By first heating the knife steel to between 1050°C and 1090°C (1922 and 1994°F) and then quickly cooling (quenching) it, the knife steel will become much harder, but also more brittle. Tempering at temperatures between 100°C and 500°C reduces the brittleness of the steel and improves toughness.
