The Paragon KM45 Knife Making Kiln is designed for swordsmiths, professional bladesmiths, educators, and fabrication shops that require maximum chamber length for full-size swords, long blades, tooling, and batch heat treating operations. Featuring a spacious 45" deep firing chamber, advanced touchscreen controls, and rugged firebrick construction, the KM45 provides the capacity, precision, and consistency needed for demanding professional heat treating applications.
Bringing heat treating in-house gives makers complete control over every stage of the thermal process. The KM45 allows users to manage normalization cycles, hardening temperatures, tempering schedules, soak times, and cooling profiles without relying on outside heat treating services. Whether refining edge hardness, experimenting with new steels, reducing blade warpage, or optimizing production workflows, the KM45 delivers the repeatability required for professional-quality results.
The kiln's chamber measures 5.5" wide, 4.3" high, and 45" deep, making it the longest chamber in the KM Base series. This extended length provides ample space for full-length swords, machetes, long chef knives, tooling, punches, dies, and multiple blades processed simultaneously. Its large firing chamber makes it an excellent choice for professional swordsmiths, custom knife shops, training programs, research facilities, and manufacturers working with extended metal components.
Built with 3" firebrick insulation, the KM45 delivers exceptional thermal retention and even heat distribution throughout the firing chamber. This heavy-duty insulation promotes stable chamber temperatures, improved energy efficiency, and highly consistent heat treating performance. Recessed heating elements are installed in precision-machined grooves to help maximize element life while simplifying future maintenance.
The KM45 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, precise temperature regulation, and enhanced long-term reliability compared to traditional mechanical relays. The SSR system is mounted on an aluminum heat sink and backed by a mechanical safety 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 KM45 is available with either a drop-door or side-swing door configuration. The drop-door design creates a convenient loading surface for long blades and tooling, while the side-swing option provides traditional chamber access with a smaller operational footprint. Combined with its heavy-duty steel exterior and integrated stand, the KM45 is engineered for years of service in professional bladesmithing shops, fabrication facilities, educational programs, and production environments.
Controller
The Paragon KM45 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 support safe and efficient blade processing, this kit includes blade holders, firebrick supports, heat-resistant gloves, and a 31" loading fork for handling long blades and tooling.
Drop Door or Side-Swing Door Configuration
Choose the chamber access style that best fits your workflow. Both configurations are available to accommodate different shop layouts and loading preferences.
