Good Kilns has applied it's kiln manufacturing skills to produce a new and affordable way for the knife maker to heat-treat and temper almost any knife blades. Chamber dimensions are 24" (D) x 8-3/4" (W) x 6" (H). The kiln operates with an infinite switch and pyrometer.

Kiln comes with stand and two extra firebrick, ready to slot, one--one for the heat treating process, and one for cooling the blade after it is removed from the oven. Truck freighted.
