KM45 Double Barrel Knifemaking Kiln

PARAGON KM45 Double Barrel: Built for Big Blades and Demanding Cycles

The PARAGON KM45 Double Barrel was created for professional bladesmiths and heat-treating specialists who require a spacious, reliable kiln to handle long blades, high-temperature workloads, and demanding thermal cycles. Designed and manufactured with precision in Mesquite, Texas, this powerful 240V kiln is part of Paragon’s trusted KM Series and built with firebrick for rugged durability and time-tested performance.

Why Have a Heat-Treating Kiln at Home or in Your Workshop

For knifemakers and metalworkers, owning your own kiln unlocks total control over the heat-treating process. Say goodbye to outsourcing delays, inconsistent results, or guesswork with torches. A dedicated kiln lets you normalize, harden, and temper blades precisely—on your schedule, to your exact specifications. Whether you're refining Damascus patterns, working with high-alloy tool steels, or producing high volumes, an in-house kiln saves time, increases consistency, and elevates your craftsmanship.

Why Choose the PARAGON KM45 Double Barrel

The PARAGON KM45 Double Barrel offers a significantly larger interior than the standard KM models. It features a wide chamber measuring 13.25 inches across, 5.25 inches high, and 45 inches deep—ideal for extra-long blades or batch processing. Built with 3" thick insulating firebrick and a rigid steel case, the KM45 Double Barrel is designed for long-term performance and exceptional thermal stability.

All heating elements are recessed into the firebrick to minimize scale, and the industrial-grade design includes a special-limit thermocouple for accuracy and durability. This model comes equipped with a drop-down door for easy front access—ideal for resting blade blanks on quench plates without touching hot coils.

The included SENTINEL controller gives you precise control of ramp rates, hold times, and soak cycles with a modern touchscreen interface that stores multiple heat-treating profiles. Whether you’re cycling 1095 or holding at high temps for CPM steels, the SENTINEL makes repeatability easy.

Who Is the KM45 Double Barrel For

This kiln is built for serious users: professional knifemakers, swordsmiths, production shops, and schools that need to process multiple blades in a single cycle or work with oversized projects. It’s especially suited to those heat treating long chef knives, swords, chisels, or batches of smaller blades. If you’ve outgrown your current kiln’s depth or chamber width, this is your natural upgrade.

Upgrade Options and Accessories

The PARAGON KM45 Double Barrel is compatible with our optional Gas Injection Flow Meter, which allows for a controlled inert atmosphere during heat treating. This reduces scale and decarb on the blade surface when using argon or other shielding gases. You can also add a digital pyrometer or the Paragon knifemaking heat-treating kit for additional precision and process control.
