The Paragon KM24 Knife Making Kiln is designed for bladesmiths, knifemakers, educators, and fabrication shops that require additional chamber length for longer blades, batch processing, and specialty metal components. With a spacious 24" deep firing chamber, advanced digital controls, and rugged firebrick construction, the KM24 provides the capacity, precision, and consistency needed for demanding professional heat treating applications.
For serious makers, bringing heat treating in-house creates opportunities that simply aren't possible when relying on outside services. The KM24 provides complete control over normalization cycles, hardening temperatures, tempering schedules, soak times, and cooling profiles. Whether refining a proven process, experimenting with exotic steels, or optimizing performance across multiple blade designs, the KM24 allows users to achieve repeatable, professional-grade results while maintaining full control over every stage of production.
The kiln's chamber measures 5.5" wide, 4.3" high, and 24" deep, providing ample space for large chef knives, swords, machetes, tooling, Damascus billets, and multiple blades processed simultaneously. Its generous chamber depth makes it an excellent choice for professional bladesmiths, growing workshops, educational programs, and makers seeking greater flexibility without stepping into a much larger industrial furnace platform.
Built with 3" firebrick insulation, the KM24 delivers exceptional thermal retention and stable chamber temperatures throughout the firing cycle. This heavy-duty insulation helps maintain consistent heat distribution while reducing energy consumption and supporting precise, repeatable heat treating performance. Recessed heating elements are installed in precision-machined grooves to help maximize element life and simplify future maintenance.
The KM24 features the SENTINEL Touch Xpress touchscreen controller with fully customizable Ramp-Hold programming capabilities. Users can create, store, and repeat custom heat treating schedules while monitoring real-time chamber temperatures through an intuitive touchscreen interface designed specifically for thermal processing applications.
A solid-state relay system comes standard, delivering quiet operation, enhanced temperature accuracy, and improved long-term reliability compared to traditional mechanical relays. The SSR system includes a heat sink and mechanical backup relay for dependable operation in demanding workshop environments. A built-in safety door switch automatically disables power to the heating elements whenever the door is opened.
The standard drop-door design provides excellent access to the firing chamber while creating a convenient loading surface for blades, fixtures, and tooling. For makers who prefer a traditional side-opening configuration, an optional swing door is also available. Combined with its heavy-duty steel exterior and integrated stand, the KM24 is built to withstand years of service in active bladesmithing shops, fabrication facilities, and educational settings.
Controller
The Paragon KM24 features the SENTINEL Touch Xpress Controller with advanced touchscreen Ramp-Hold programming capabilities. Easily create and store custom heat treating schedules, control soak times and cooling cycles, and monitor real-time chamber temperatures with precision and repeatability.
Optional Upgrades
Gas Injection Flow Meter
Available as either a kit or factory-installed option, the Gas Injection Flow Meter introduces inert gas such as argon or nitrogen into the chamber to help reduce oxidation, decarburization, and scale formation during heat treating cycles. By displacing oxygen within the firing chamber, the system can reduce or eliminate the need for stainless steel foil while helping improve blade finish quality, preserve crisp grind lines, and minimize post-processing cleanup.
Solenoid Valve Upgrade
Works alongside the Gas Injection Flow Meter to automate gas flow during firing cycles. Gas can be programmed to flow only during specific firing segments, improving efficiency, reducing gas consumption, increasing safety, and supporting highly repeatable heat treating environments.
Knifemaking Heat Treating Kit
Designed to keep blades upright, evenly spaced, and properly positioned throughout the firing cycle for more consistent heat distribution and improved heat treating results.
Swing Door Option
Available for makers who prefer a traditional side-opening chamber design instead of the standard drop-door configuration.
