Authorized Paragon dealer · full factory warranty

Brand new and shipped direct from Paragon, so it carries Paragon's full factory warranty. If something goes wrong, call us and we handle the claim with the factory for you.

Warranty terms are in the Warranty and support section below.

Returns: request within 15 days, unused

Because kilns are heavy and often built to order, returns are limited, so we'd rather help you pick the right one up front:

  • Ask within 15 days of purchase or 2 days after delivery, whichever comes first. We issue a return authorization (RA).
  • It must be new, unused (beyond the factory test fire) and in its original packaging.
  • A restocking fee of at least 25% applies, up to 50% on custom, 3-phase or made-to-order units. Return freight is on the buyer unless we made an error.
  • Damaged in transit? Note it on the delivery receipt, send us photos and we'll help with the freight claim.

Will it work in my space? Power check

Not included: Paragon Knifemaking Heat Treating Kit (gloves, tongs, blade holders, firebrick supports) and gas inlet/flowmeter, both optional upgrades. Requires 240V. Call us to confirm the plug type for your shop before ordering.

Most 240V kilns need their own circuit and the matching outlet, installed by an electrician. Homes are usually 240V; schools and commercial buildings are often 208V, so pick the voltage that matches your panel.

Send us a photo of your breaker panel or outlet and we'll confirm before your kiln is built: 470-264-3563 (call or text).

Overview

Paragon · Heat Treating Oven · Double Barrel Knife Oven Paragon Double Barrel KM9 Pro Knife Heat Treating Oven KM9 Pro · 240V · Extra-Wide Chamber · Fires to 2350°F The Double Barrel KM9 Pro features one extra-wide 13-inch chamber that lets you heat treat more blades in a single load, increasing workshop productivity. Space-age ceramic fiber construction delivers exceptionally fast heating—reaches 500°F in minutes—enabling rapid turnaround times for blade tempering and hardening. This professional-grade furnace reaches a maximum temperature of 2350°F, ideal for heat treating high-carbon and tool steels commonly used in knife making.

What’s included
The oven, assembled and wiredParagon builds and wires it at the factory. The door style you chose is already fitted: a spring-assisted drop door or a side-swing door, both standard at the same price.
Digital controller, factory-installedParagon fits and wires the controller before the kiln leaves the factory. Paragon has been renaming and replacing its controller line and dealer listings are out of date at different dates, so we do not print a model name here. We confirm the exact controller with Paragon when you order.
Type-K thermocouple, installedFitted at the factory and wired to the controller. Type-K is standard across the current Paragon range.
Door safety switchWired in at the factory. It cuts power to the elements the moment you open the door, so you are not reaching into a live chamber.
Cord and plugParagon ships this kiln with a cord and plug. The receptacle type changes with the voltage option you order, so we confirm the exact plug — or whether your configuration is wired direct instead — with Paragon before the order goes in.
Printed manualsA printed instruction manual for the kiln and a separate guide for the controller. Warranty registration is done online at Paragon, and we do not promise a printed warranty card in the crate because we could not confirm one is packed.
Paragon limited warranty — one yearOne year from purchase on this model, per Paragon's published warranty schedule. Paragon does not warrant the Type-K thermocouple, so treat that as a wear part. Keep your proof of purchase.
Not includedNo shelves, posts or kiln furniture ship with a knife oven. The Knifemaker's Heat Treating Kit — four knife holders, eight firebrick supports, a heat treating fork and hot gloves — is a separate purchase, and so are the upgraded touchscreen controller and the gas-inlet option.

Common questions
What types of steel can I heat treat in the KM9 Pro?
The KM9 Pro reaches 2350°F, making it suitable for heat treating high-carbon steels (1095, 1084, 1075), tool steels (O1, A2, D2), and many stainless knife steels (440C, AEB-L, 154CM). It provides sufficient temperature for austenitizing most common blade steels. For ultra-high alloy steels like S30V or M4 that require higher temperatures, consult steel-specific heat treating specifications.
Do I need a gas inlet for atmosphere control?
A gas inlet is optional but highly recommended for professional knife making. Introducing inert gases like argon or nitrogen creates a protective atmosphere that prevents oxidation and decarburization during heat treating, resulting in cleaner blades that require less post-heat-treat grinding. The standard KM9 Pro can be retrofitted with a gas inlet kit.
What controller comes standard with the KM9 Pro?
The KM9 Pro includes a single-zone Sentinel touchscreen controller with precision temperature monitoring and control. The controller allows you to set specific soak times and temperatures for consistent hardening and tempering cycles. Paragon's heat treating ovens are designed specifically for knife making applications with reliable, repeatable temperature control.
How does the double barrel design improve workflow?
The Double Barrel has a single chamber that is much wider than the standard KM9 Pro (13 inches wide), so you can load more blades side by side in one cycle. It is one chamber with one controller, so everything in a load runs the same program, but the extra width increases daily production capacity.
Is the warranty valid if I buy from Peach State Pottery?
Yes. Peach State Pottery is an authorized Paragon dealer, which means your oven qualifies for the full manufacturer's warranty. You must register your oven with Paragon within 30 days of delivery. Warranty claims are handled directly through Paragon, and purchasing from an authorized dealer ensures you receive genuine Paragon support and service.
