Paragon 6.8L Knife Maker’s Heat Treating Furnace

SKU: K-PA-KM18T
Coming soon

$2,520.25

When you own a Paragon KM-18T furnace, you can live the knife making adventure to the fullest. You will actually witness the birth of your knives in the bright red heat of the furnace. The soul is born in the furnace, because the heat treating brings out the highest qualities of the steel. 

Many knifemakers enjoy owning a furnace, because they can revel in testing. They put blades through tests more severe than any knife owner would dare. Yes, they test for Rockwell hardness, but they don’t stop there. The serious knifemaker tests the knife against hemp rope and 2x4s. They 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 knife maker with a KM-series furnace can try exotic heat treating methods at his leisure. Does quenching in dry ice improve blade performance? What happens when 52100 steel is triple-quenched with a one-day wait between each quench? After this treatment, will a 52100 blade bend to 90° without chipping? 

With a Paragon furnace in your shop, all questions about heat treating formulas are settled. Heat treating is no longer theory. You find out for yourself what works. Testing and heat treating is at the heart of the knife making adventure. Here is where your confidence as a knife maker takes root. Through heat treating, you can master a tool steel and make it your own. 

Experiment with differential hardening, an ancient bladesmith technique. Try out the newest tool steels. Are they really as good as the tried and true D2 and A2? Paragon’s knifemaking furnaces are now rated to 2350 degrees F, so you can heat treat as hot as you need to.

Door safety switch

The door micro safety switch shuts off the power to the elements when the door is opened, yet the controller continues to give a temperature readout. The safety switch is standard on Paragon KM furnaces.

Solid furnace construction

The furnace is insulated with 3” thick refractory firebrick, which is 1/2” thicker than the standard. The elements are mounted in dropped, recessed grooves machined into the firebrick. This groove protects the element for long life and low maintenance. Elements are simple to replace because they can be lifted directly from the groove. You can replace elements following instructions in the printed manual. 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 control box for protection from the harsh environment of the typical bladesmith shop.
