    PARAGON KM54 Double Barrel: Go Bigger. Treat Smarter.

    The PARAGON KM54 Double Barrel is the longest, widest, and tallest kiln in the KM lineup. With a full 54" of depth and the spacious Double Barrel chamber profile, this kiln was built for swordsmiths, high-volume shops, and professionals pushing the limits of size, complexity, and heat treating precision.

    Why Have a Heat Treating Furnace in Your Shop?

    When you're making serious blades, control isn’t optional—it’s essential. The KM54 Double Barrel gives you full authority over the heat treating process, from custom ramp rates to extended soaks, atmospheric protection, and beyond. Whether you're hardening 50 blades or refining a new steel formula, this kiln delivers the space and stability to do it right.

    Why Choose the PARAGON KM54 Double Barrel?

    This is the largest standard kiln we offer for knife making and heat treating. With its massive chamber and rugged construction, the KM54 Double Barrel gives you full freedom to work with oversized pieces, multiple blades, and intricate setups—all in a single cycle.

    • SENTINEL Touch Xpress controller: Advanced touchscreen control with fully customizable ramp/hold programs and easy recall for repeat jobs.

    • Solid-state relay: Quiet, reliable, and highly accurate. Includes aluminum heat sink and safety backup relay for peace of mind.

    • 3” firebrick insulation: High-efficiency insulation for consistent temperature profiles and low energy loss.

    • Recessed heating elements: Protected in machined grooves for extended element life and easy servicing.

    • Reinforced steel construction: Built tough for full-time use, with a heavy-duty stand for elevation and ventilation.

    Who is This Furnace For?

    The KM54 Double Barrel is ideal for:

    • Swordsmiths working with full-length blades like katanas, sabers, and longswords

    • Makers treating large batches, jigs, or long tooling setups

    • High-output knife shops requiring broad, deep, and tall chamber space

    • Schools and industrial R&D labs running extended or experimental heat cycles

    Its 54" length, combined with the 13" width and 5.3" height, makes this the most spacious and capable kiln in the series.

    Drop Door Only

    All KM Double Barrel kilns come with a Drop Door—ideal for loading long or multiple items, and providing a staging platform while open.

    Optional Upgrades

    • Gas Injection Flow Meter: Displace oxygen with inert gas (e.g., argon) to reduce scaling. Available as an add-on kit or pre-installed.

    • Add a solenoid valve: For automated, safe gas delivery—only flows during active segments of your firing program.

    • Knifemaking Kit: Keep blades upright and aligned for balanced heat distribution during hardening.

    Built with Pride in Mesquite, Texas

    Every PARAGON KM54 Double Barrel is handcrafted by skilled technicians in Mesquite, Texas. It’s the ultimate choice for bladesmiths who need capacity, control, and proven reliability in one elite furnace.
