    All KM Series Paragon Knife Making Furnaces come standard with a Guillotine (drop-down) Door mounted on a heavy-duty 1/2 thick hinge shaft for smooth opening. A counter-weight handle on the drop-down door allows for one-handed operation and assures the door is securely closed. The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The sidewall elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. The elements in the top are seated in pinless element grooves. The firing chamber is protected by a rigid steel case. A built-in solid stand lifts the firing chamber safely off your worktable. The thermocouple wire is kept inside the case for protection from the harsh environment of the typical bladesmith shop.
