    PARAGON KM24 Double Barrel: Full-Length Heat Treating with Room to Spare

    The PARAGON KM24 Double Barrel is built for bladesmiths who push the limits of length, width, and complexity. With a full 24" chamber depth and a wide, tall interior profile, this kiln handles everything from long chef’s knives and swords to side-by-side batches and tall workpieces—giving you uncompromising versatility and control.

    Why Have a Heat Treating Furnace in Your Shop?

    Serious bladesmiths don’t just make knives—they engineer performance. The KM24 Double Barrel gives you full autonomy over time, temperature, and technique. No waiting on heat treating services. No wondering about results. With this kiln, you refine your own formulas, experiment confidently, and take your heat treating from good to exceptional.

    Why Choose the PARAGON KM24 Double Barrel?

    Designed for professional bladesmiths and high-output shops, the KM24 Double Barrel combines generous capacity with industrial-grade performance in a format that fits most workshops. The added chamber width and height give you more freedom to heat treat a variety of projects—without crowding or compromise.

    • SENTINEL Touch Xpress controller: Advanced touchscreen control for fully programmable ramp, hold, and cool-down cycles.

    • Solid-state relay: Provides quiet, durable operation with superior temperature accuracy. Includes heat sink and backup safety relay.

    • 3” firebrick insulation: Retains heat efficiently for uniform soak temperatures and energy savings.

    • Recessed heating elements: Safely mounted in precision-machined grooves for long-term reliability.

    • Reinforced steel construction: Built tough with a built-in stand for proper ventilation and stability.

    Who is This Furnace For?

    The KM24 Double Barrel is ideal for:

    • Bladesmiths producing long, wide-profile blades like chef’s knives, bushcraft knives, kukris, or short swords

    • Makers who prefer treating multiple blades or components in a single run

    • Workshops using jigs or fixtures that require more vertical or lateral space

    • Schools or labs working with varied tool geometries or extended cycle testing

    Its full 24" depth combined with the spacious cross-section makes it one of the most versatile and capable furnaces in the lineup.

    Drop Door Only

    All KM Double Barrel kilns are equipped with a Drop Door, offering the best access to the wide chamber and a convenient staging surface when open.

    Optional Upgrades

    • Gas Injection Flow Meter: Reduce scale by replacing oxygen inside the kiln with inert gas (argon, nitrogen, etc.). Available as a kit or factory-installed.

    • Add a solenoid valve: Automatically manages gas flow during your program—only flows when needed for safety and savings.

    • Knifemaking Kit: Hold and align blades for consistent and efficient hardening during every cycle.

    Built with Pride in Mesquite, Texas

    Every PARAGON KM24 Double Barrel is handcrafted in Mesquite, Texas, with precision, durability, and the needs of the modern bladesmith in mind. It’s the tool that gives you space to grow—literally and creatively.
