Paragon KM24 Double Barrel Knife Making Oven

Built for bladesmiths, educators, fabrication shops, and high-output knife makers needing greater chamber length and expanded working space, the Paragon KM24 Double Barrel delivers precise digital heat treating performance for knives, tooling, and specialty metal components. Its full 24" chamber depth combined with a wider, taller chamber profile provides outstanding flexibility for long blades, taller fixtures, and side-by-side batch processing. The Paragon KM24 Double Barrel is designed for makers who require additional chamber capacity without stepping into a large industrial furnace platform. Whether heat treating chef’s knives, bushcraft blades, kukris, short swords, tooling, or custom fabricated components, the KM24 Double Barrel offers the chamber space, repeatability, and thermal consistency needed for reliable professional results. Heat treating in-house gives makers complete control over normalization, hardening, tempering, soak schedules, and experimentation while eliminating the delays and expense associated with outsourcing. The KM24 Double Barrel allows users to fine-tune ramp rates, hold times, cooling cycles, and firing profiles for repeatable blade performance and process refinement. The kiln’s 3" firebrick insulation provides excellent thermal retention and stable chamber temperatures for accurate, energy-efficient heat treating cycles. Recessed heating elements are installed in precision-machined grooves to help extend element life and simplify future maintenance. The KM24 Double Barrel features the SENTINEL Touch Xpress touchscreen controller with fully customizable Ramp-Hold programming capabilities. Easily create and store custom heat treating schedules while monitoring real-time chamber temperatures through the intuitive touchscreen interface. A solid-state relay system comes standard, delivering quiet operation, improved temperature accuracy, and extended service life compared to traditional mechanical relays. The SSR system also includes an integrated heat sink and backup safety relay for dependable long-term operation in demanding shop environments. All KM Double Barrel models feature a drop-door design exclusively, providing excellent chamber access and a convenient staging surface for blades and tooling when the door is open. The reinforced steel exterior and built-in stand are engineered for the daily demands of active bladesmithing shops, educational programs, and fabrication environments. Controller The Paragon KM24 Double Barrel 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 system introduces inert gas such as argon or nitrogen into the chamber to help reduce oxidation and scale formation during heat treating cycles. This can help minimize foil wrap use while improving blade finish consistency and reducing cleanup. Solenoid Valve Upgrade Works alongside the gas injection system to automate gas flow during firing cycles for improved efficiency, repeatability, and control. Gas flows only when needed, helping reduce waste while supporting more consistent atmospheric conditions. Knifemaking Heat Treating Kit Designed to help keep blades upright, evenly spaced, and properly positioned for more consistent heat distribution during firing cycles.
