Paragon KM14 Double Barrel Knife Making Oven

Built for knifemakers, bladesmiths, educators, and fabrication shops needing greater chamber capacity without moving to a large industrial furnace, the Paragon KM14 Double Barrel delivers precise digital heat treating performance for knives, tooling, and small metal components. Its wider, taller chamber and generous 14.5" depth provide additional flexibility for broad blades, taller fixtures, and side-by-side batch processing.

The Paragon KM14 Double Barrel is designed for makers who need more room to work with serious steel while maintaining accurate, repeatable thermal performance. Whether heat treating kitchen knives, outdoor blades, cleavers, kukris, tooling, or custom fabricated parts, the KM14 Double Barrel offers the chamber space and control needed for consistent professional results.

Heat treating in-house gives makers complete control over hardening, tempering, soak schedules, and experimentation while eliminating the delays and expense associated with outsourcing. The KM14 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 KM14 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 improved chamber access and a convenient resting platform for blades and tooling when the door is open. The heavy-duty steel exterior and built-in stand are engineered for the daily demands of active bladesmithing shops, educational programs, and fabrication environments.

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.

Higher voltage means lower amperage draw and greater efficiency, which can save money long term. 240V and 208V cost the same—most home studios use 240V, while 208V is common in schools or large facilities. Amperage refers to the amount of electrical current a kiln draws—higher amps require heavier wiring and breakers.

Single-phase is what almost all homes have. If your facility has three-phase, you can choose either—but three-phase is typically the better long-term option due to smoother power and improved efficiency.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.

The following controllers are used across kilns sold by Pottery Pulse. Not all models offer every option—available controllers are listed on each product page. Some kilns include only the standard controller, while most allow upgrades for added precision and convenience.

Not all kilns can use a collar, but Olympic’s Hot Box kilns can be ordered with a collar to expand versatility. A blank collar simply adds height to the firing chamber, while a bead collar adds the same height and includes a built-in bead or annealing door for quick-access lampwork projects.

This safety feature automatically cuts power to the heating elements whenever the kiln lid or door is opened. It prevents accidental burns, protects elements, and resumes power only when safely closed. (Also called an automatic lid shutoff on Olympic kilns.)
