PARAGON KM24: Built for Blades That Push the Limit

The PARAGON KM24 offers serious chamber length for serious makers. With 24" of interior depth, this kiln is designed to accommodate longer knives, swords, machetes, and batch runs—while maintaining the precision, durability, and performance that define the KM Base line.

Why Have a Heat Treating Furnace in Your Shop?

A heat treating furnace in your shop doesn’t just improve your knives—it transforms the way you work. Want to test exotic steels? Perfect differential hardening? Dial in your own multi-cycle quenching process? With the KM24, you gain the freedom to experiment, optimize, and push your heat treating knowledge far beyond the basics. The result? Knives that not only look great but perform under extreme conditions.

Why Choose the PARAGON KM24?

The KM24 offers a long chamber without jumping to an industrial footprint. It’s a favorite among professionals who work on extended blades or heat treat in batches. Built with robust insulation and smart design, it’s a high-performance machine for high-performance steel.

  • Interior chamber: 5.5" W x 4.3" H x 24" D (0.33 cubic feet)

  • SENTINEL Touch Xpress controller: Touchscreen with user-friendly programming to control every stage of your cycle

  • Solid-state relay: Silent, reliable, and precise—equipped with heat sink and backup safety relay

  • 3” firebrick insulation: Provides efficient heat retention for consistent and repeatable cycles

  • Recessed heating elements: Positioned in deep grooves to reduce wear and simplify replacement

  • Steel case with built-in stand: Rugged and reliable, ready for the demands of a full-time shop

Who is This Furnace For?

The KM24 is ideal for:

  • Bladesmiths working with swords, machetes, and large chef knives

  • Knifemakers who prefer to heat treat multiple blades at once

  • Professionals who require deeper soak zones for even heat distribution

  • Workshops scaling up from smaller kilns into more versatile production

Its 24" length makes it a go-to choice for shops that want long-capacity firing without excess bulk.

Choose Your Door Style

The KM24 is available in two configurations:

  • Swing Door – Side-opening for efficient access and compact shop layouts

  • Drop Door – Downward-opening for easier loading and a convenient surface

Optional Upgrades

  • Gas Injection Flow Meter: Introduce inert gas to reduce oxidation and scale during firing.

  • Add a solenoid valve: Automatically controls gas flow—only active when needed.

  • Knifemaking Kit: Securely holds blades upright and evenly spaced for consistent thermal exposure.
