When it ships & how it's delivered · freight to your door

Paragon builds most kilns to order once your order is placed. We email your confirmed ship date and tracking.

  • The freight carrier calls you to book a delivery window.
  • Delivery is curbside with a liftgate. Have a helper or hand truck to move it inside.
  • Check the crate before you sign. Note any damage on the receipt and send us photos.

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 · Knife Making Paragon Knife Oven – KM24 KM24 · 240V · 24" chamber depth · Fires to 2350°F · Professional heat treating Professional knife heat treating oven engineered specifically for blade makers, featuring a 24-inch deep chamber that accommodates multiple blades or longer knives in a single firing cycle. Reaches a maximum temperature of 2350°F for proper heat treating, hardening, and tempering of high-carbon steels and tool steels commonly used in blade making. Runs on 240V single-phase power, with standard or advanced controller options to match your workshop requirements.

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 plug — NEMA 6-20RParagon fits a cord with a NEMA 6-20R plug. The plug changes with the voltage option you order, so tell us your service and we confirm the receptacle 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 KM24?
The KM24 reaches 2350°F, making it suitable for heat treating high-carbon steels (1095, 1084, 1075), tool steels (O1, A2, D2), and most popular knife-making steels. This temperature range covers austenitizing temperatures for hardening as well as lower tempering ranges. Stainless steels requiring higher temperatures (like 440C or S30V) may need specialized equipment, but the KM24 handles the vast majority of carbon and alloy steels used by custom knife makers.
Do I need a gas inlet port for atmosphere control?
A gas inlet port is optional but recommended for professional knife makers concerned with oxidation and decarburization. The optional atmosphere port allows you to introduce inert gases like argon or nitrogen, or use specialized atmosphere-control systems to protect blade surfaces during heat treating. Many makers successfully heat treat without atmosphere control by using foil wraps or anti-scale compounds, but a controlled atmosphere provides the cleanest results and eliminates surface grinding.
What controller comes standard, and are upgrades available?
The KM24 comes standard with a digital controller that offers programmable ramp/hold segments for creating precise heat treating cycles. This allows you to program specific heating rates, soak times, and cooling protocols essential for proper heat treatment. An advanced controller upgrade is available, offering additional programming segments, enhanced accuracy, and more sophisticated control features for knife makers running complex or experimental heat treating schedules.
How does the KM24 compare to other Paragon knife ovens?
The KM24's defining feature is its 24-inch chamber depth, which accommodates longer blades like swords, machetes, and oversized chef knives, or allows batch processing of multiple smaller blades. Smaller Paragon knife ovens offer similar temperature ranges and capabilities but with shorter chambers suited for standard knife lengths. The KM24 is ideal for makers who regularly work with longer blades or need higher production capacity in a single firing cycle.
Can I purchase this oven through any dealer, and how does warranty work?
Paragon warranties are only valid when purchased through authorized dealers like Peach State Pottery. Purchasing from unauthorized sellers or second-hand sources typically voids manufacturer warranty coverage. You must register your oven within 30 days of delivery to activate the one-year limited warranty. As an authorized Paragon dealer, Peach State Pottery provides full warranty support, technical assistance, and access to genuine replacement parts throughout your oven's lifetime.
