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 · Double Barrel Knife Oven Paragon Knife Oven - Double Barrel KM24 Pro KM24 Pro · 240V · Extra-Wide 24" Chamber · Fires to 2350°F The Double Barrel KM24 Pro features one extra-wide 24-inch chamber with 3-zone control, so you can heat treat larger batches of blades in a single load. Advanced ceramic fiber construction reaches 500°F in minutes, dramatically reducing cycle times compared to traditional brick ovens. Precision temperature control up to 2350°F ensures proper hardening and tempering of high-carbon steels, stainless steels, and tool steels.

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 KM24 Pro?
The KM24 Pro fires to 2350°F, making it suitable for hardening and tempering high-carbon steels (1095, 1084, 1075), stainless steels (440C, AEB-L, 154CM), and tool steels (D2, A2, O1). The extra-wide chamber lets you process larger batches of the same steel in one cycle.
Do I need a gas inlet for protective atmosphere?
A gas inlet port is optional but recommended for professional bladesmiths who want to prevent oxidation and decarburization during the hardening process. The port allows you to introduce argon, nitrogen, or other protective gases into the chamber. It's available as an optional accessory and can be installed at time of purchase or added later.
What controller comes standard with the KM24 Pro?
The KM24 Pro Double Barrel includes a Sentinel touchscreen controller with 3-zone control and programmable temperature ramps and holds. You can create multi-step heat treating profiles for precise control over hardening, soaking, and tempering cycles. For advanced features like Wi-Fi monitoring and expanded profile storage, the Genesis touchscreen is available as an upgrade.
How does the KM24 Pro compare to single-chamber knife ovens?
The Double Barrel has one chamber that is much wider than the standard KM24 Pro, so you can heat treat more blades per load. It is one chamber with one 3-zone controller, so everything in a load runs the same program while the three zones keep heating even. The ceramic fiber construction heats faster than brick ovens, reaching 500°F in minutes rather than an hour or more.
Do I need to purchase this through an authorized dealer for warranty coverage?
Yes. Paragon's one-year limited warranty is only valid on kilns purchased through authorized dealers like Peach State Pottery. The warranty must be registered within 30 days of delivery. Unauthorized dealers, used equipment, and private-party sales are not covered under manufacturer warranty.
