PARAGON KM24 Pro Double Barrel: Built for Bladesmiths Who Think Big
The PARAGON KM24 Pro Double Barrel is made for makers who push the limits—of blade size, batch volume, and thermal control. With its expansive chamber and 24" depth, this kiln offers the interior space professionals need, backed by the advanced 3-zone precision of the KM Pro Series.
Why Have a Heat Treating Furnace in Your Shop?
When you control your heat treatment, you control your results. With the KM24 Pro Double Barrel, you’re not just running blades through a cycle—you’re dialing in soak zones, experimenting with steels, and ensuring every inch of every blade is hardened exactly as intended. Whether you’re heat treating ten blades at once or just one very long one, this kiln makes sure they all come out right.
Why Choose the PARAGON KM24 Pro Double Barrel?
The KM24 Pro Double Barrel gives you industrial-grade features in a format that still fits comfortably in most serious knife shops. With 3-zone control, ceramic fiber insulation, and a chamber built for big work, it offers unmatched flexibility and performance.
3-Zone Temperature Control: Three exposed-tip thermocouples (front, center, and rear) monitored independently by the SENTINEL controller to ensure perfect uniformity.
Special Limit Thermocouples: Fast-response, 14-gauge exposed tips for precise temperature readings across the entire load.
Solid-State Relays: Three SSRs mounted on aluminum heat sinks—quiet, long-lasting, and exceptionally accurate. Includes safety backup relay.
2.5” Ceramic Fiber Insulation: Heats faster, cools quicker, and holds tight soak temps with less energy use.
Surface-Mounted “Wavy” Elements: Broad, even heating and long element life from wall-mounted layout.
Guillotine Door: The spring-assisted vertical-opening door lifts up and away from the user, keeping the hot face safely out of the way and eliminating the need for clearance around the kiln.
Heavy-duty steel cabinet with integrated stand: Built for demanding shops and extended duty cycles.
Who is This Furnace For?
The KM24 Pro Double Barrel is ideal for:
Bladesmiths making long, wide-profile blades or tools
Makers running large batch loads in jigs or fixtures
Professionals requiring even temperature across big projects
Schools and labs needing consistent, multi-zone thermal control for research or training
Optional Upgrades
Gas Injection Flow Meter: Reduce scaling by displacing oxygen in the chamber with argon or other inert gas.
Add a solenoid valve: Automatically controls gas flow—active only during programmed segments for added safety.
Knifemaking Heat Treating Kit: Includes firebrick supports, blade holders, heat-resistant gloves, and a 31" fork for safe, efficient blade handling.
