    PARAGON KM45: For Blades That Stretch the Limits

    The PARAGON KM45 is made for knifemakers and swordsmiths who need serious chamber depth. With a 45" interior, this kiln gives you the space to work with full-length swords, long chef knives, machetes, and batch runs—while maintaining the proven performance of the KM Base lineup.

    Why Have a Heat Treating Furnace in Your Shop?

    Having your own heat treating furnace allows you to take full ownership of your craft. It opens the door to testing steels, perfecting quench recipes, and verifying results with confidence. Whether you’re refining edge hardness, minimizing warp, or pushing tool steels to their limits, the KM45 gives you the control to do it right.

    Why Choose the PARAGON KM45?

    The KM45 offers the longest chamber in the KM Base series, while preserving the reliability and structure that bladesmiths trust. From its solid-state relay to the SENTINEL touchscreen controller, this kiln is built to deliver consistent, professional results—day after day.

    • Interior chamber: 5.5" W x 4.3" H x 45" D (0.62 cubic feet)

    • SENTINEL Touch Xpress controller: Fully programmable, intuitive interface for ramp/hold cycles and repeatable precision

    • Solid-state relay: Reliable, quiet, and efficient—includes aluminum heat sink and backup safety relay

    • 3” firebrick insulation: Durable firebrick walls provide excellent thermal retention and insulation

    • Recessed heating elements: Positioned in machined grooves to protect the elements and extend their life

    • Rigid steel case with built-in stand: Ready for workshop use and engineered for long-term performance

    Who is This Furnace For?

    The KM45 is ideal for:

    • Swordsmiths and makers working with long, single-piece blades

    • Knife shops heat treating multiple blades in a single load

    • Professionals transitioning to longer projects or larger tools

    • Training facilities and R&D labs working with extended samples

    Choose Your Door Style

    Available in two configurations:

    • Swing Door – Side-opening with minimal shop footprint

    • Drop Door – Downward-opening for improved loading flexibility and convenience

    Optional Upgrades

    • Gas Injection Flow Meter: Introduce argon or other inert gases to reduce scaling during heat treating

    • Add a solenoid valve: Automatically activates gas flow during programmed stages for increased safety and control

    • Knifemaking Kit: Includes blade holders, firebrick supports, heat-resistant gloves, and a 31" fork for safe loading and unloading

    Built with Pride in Mesquite, Texas

    Every PARAGON KM45 is built by hand in Mesquite, Texas and reflects decades of experience supporting bladesmiths and metalworkers worldwide. When your craft stretches the limits of length and control, the KM45 is your trusted tool.
