Paragon Ovens - Jantz's Top Choice For Heat Treating

Paragon Furnaces are high-quality ovens and kilns used for heat treating knives. In our experience, Paragon represents the best in quality and customer service of any kiln and furnace manufacturer.  Made in Texas, Paragon stands behind its products and is a supportive part of the knife making community.

Kilns will complete the entire heat treating process, including annealing, normalizing, hardening, and tempering.

Paragon Furnaces are equipped with a door safety switch that shuts off power when the door is opened while continuing to give a temperature readout on the controller.

Featuring a quiet, long-lasting, Solid State Relay with no moving parts to wear out so heating elements last longer and offer better temperature control during holds.  (18" oven has a mechanical relay as part of a safety circuit). 

Paragon ovens come in a variety of depths and are available in single or double barrel widths. The maximum temperature of these kilns is 2350°F.

Paragon ovens come standard painted deep black or you can special order in berry, black, blue, hot pink, jade, navy, purple, or turquoise at no additional charge. 

Paragon Furnaces ship free to the contiguous 48 states.

Please allow 4-6 weeks for delivery or call to check for ready to ship ovens.
