Built for knifemakers, bladesmiths, educators, and small fabrication shops needing greater chamber flexibility in a compact footprint, the Paragon KM9 Double Barrel delivers precise digital heat treating performance for knives, tooling, and small metal components. Its wider and taller chamber design allows makers to heat treat broader blades, taller fixtures, and multiple pieces side by side while preserving valuable workshop space.
The Paragon KM9 Double Barrel is designed for makers who want more working room than smaller furnace platforms without stepping into a much larger industrial unit. Whether heat treating kitchen knives, outdoor blades, folders, tooling, or small fabricated components, the KM9 Double Barrel provides the thermal precision, repeatability, and durability needed for consistent professional results.
Heat treating in-house gives makers complete control over hardening, tempering, and soak schedules while eliminating the delays and costs associated with outsourcing. The KM9 Double Barrel allows users to fine-tune ramp rates, soak times, cooling cycles, and firing profiles for repeatable blade performance and experimentation.
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 protected within precision-machined grooves to help extend element life and simplify future maintenance.
The KM9 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.
All KM Double Barrel models feature a drop-door design exclusively, providing improved chamber access and a convenient loading surface when the door is open. The rigid steel exterior and built-in stand are engineered for the daily demands of active bladesmithing shops, educational programs, and fabrication environments.
Controller
The Paragon KM9 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
Introduces inert gas such as argon or nitrogen into the firing chamber to help reduce oxidation and scale buildup during heat treating cycles. This can improve surface finish quality, reduce cleanup work, and lessen reliance on stainless foil wrap.
Solenoid Valve Upgrade
Adds automated gas-flow control for greater efficiency and consistency during firing cycles. The system regulates inert gas delivery only when needed, supporting more controlled atmospheric conditions while reducing unnecessary gas consumption.
Knifemaking Heat Treating Kit
Designed to help keep blades upright, evenly spaced, and properly positioned for more balanced heat distribution and consistent hardening results.
