Built for professional bladesmiths, swordsmiths, educators, and production shops needing exceptional chamber length and expanded working space, the Paragon KM45 Double Barrel delivers precise digital heat treating performance for knives, swords, tooling, and specialty metal components. Its extended chamber depth combined with a wider, taller chamber profile provides outstanding flexibility for long blades, oversized tooling, custom fixtures, and high-volume batch processing.
The Paragon KM45 Double Barrel is designed for makers who require substantial chamber capacity while maintaining accurate, repeatable thermal performance. Whether heat treating chef’s knives, swords, chisels, bushcraft blades, tooling, or custom fabricated components, the KM45 Double Barrel offers the chamber space, consistency, and control needed for dependable 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 KM45 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 reduce scale formation, extend element life, and simplify future maintenance.
The KM45 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 resting surface for blades and tooling when the door is open. The rigid steel exterior and integrated stand are engineered for the daily demands of active bladesmithing shops, educational programs, and fabrication environments. A built-in safety door switch automatically disables power when the door is opened.
Controller
The Paragon KM45 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, decarb, 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.
