When your Paragon KM-24D furnace arrives, you will begin to live the knife making adventure more fully. Now you can join that elite corps of knife makers who witness the birth of the knife. In the bright red heat of the furnace, the soul of the knife is born. Many furnace owners revel in testing. They put blades through tests more severe than any knife owner would dare. They test for Rockwell hardness, but they don't stop there. They count the number of cuts a knife makes on hemp rope. They measure the foot-pounds of torque required to bend the blade to 45° or even 90°. Then they straighten the blade, slap on a handle and test it in the real world.
The door swings open with one-handed operation. A counter-weight handle holds the door securely closed. The door has a vent hole, so you can see inside the furnace during firing. Metal covers seal the vent holes when not in use. (Always wear Paragon firing safety glasses when looking into a hot furnace.) The furnace is insulated with refractory firebrick. The elements are mounted in dropped, recessed grooves machined into the firebrick. Paragon invented this type of groove in 1952. This groove protects the element for long life and low maintenance. Elements are simple to replace because they're exposed rather than embedded. You can thread new elements into place following clear instructions in the manual.
The firing chamber is protected by a steel case painted in high temperature blue. A built-in stand lifts the firing chamber safely off your worktable, so no extra stand is needed. The door is mounted with a heavy-duty hinge for smooth opening. A micro-switch shuts off the power to the elements when the door is opened. We use high temperature wire in the switch box for long life. A heat shield, mounted between the switch box and furnace, helps keep the switch box components cool even during extended operation. To further dissipate heat, the switch box is extra large and generously louvered. Each furnace comes with a cord and plug for immediate installation and a one year warranty.
