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.

Enter your ZIP in the freight estimate below to see the delivered cost.

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 · Front-Loading Double Barrel Paragon Knife Oven - Double Barrel KM24 KM24 · 240V · Large Capacity Double Barrel · Fires to 2350°F (Cone 10) The Double Barrel KM24 features one extra-wide, tall 24-inch deep chamber that lets you heat treat more blades in a single load, maximizing productivity for professional knife makers and bladesmiths. The chamber reaches 2350°F with precise temperature control, ideal for heat treating high-carbon steels, stainless steels, and tool steels. Runs on 240V single-phase power.

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 Double Barrel?
The KM24 reaches 2350°F, which is sufficient for heat treating high-carbon steels (1095, 1084, W2), stainless steels (440C, AEB-L, 154CM), tool steels (O1, A2, D2), and Damascus steel. This temperature range covers the austenitizing temperatures for virtually all common knife-making alloys. For specialty stainless steels requiring atmosphere control, consider adding the optional gas inlet kit to prevent oxidation during heat treating.
Do I need the gas inlet for atmosphere control?
The gas inlet is optional and depends on your steel types and desired finish. For most high-carbon steels, air atmosphere is sufficient since you'll grind away scale during finishing. For stainless steels or when you want to minimize decarburization and surface oxidation, the gas inlet allows you to introduce argon or nitrogen for a protective atmosphere. Many professional knife makers start without it and add it later as their production demands increase.
What controller comes standard with this oven?
The KM24 includes a Sentinel Touch Xpress touchscreen controller with ramp and hold capabilities, allowing you to set target temperatures and soak times for proper heat treating cycles. You can upgrade to the Genesis touchscreen controller for more advanced programming features including 8-segment profiles, temperature graphing, and the ability to store multiple custom programs for different steel types.
How does the Double Barrel KM24 compare to single-chamber knife ovens?
The Double Barrel has the same 24-inch depth as the standard KM24 but a wider, taller chamber, so you can load more blades per cycle or fit wider pieces. It is one chamber with one controller, so everything in a load runs the same program. For small batch or hobby knife makers, the standard KM24 may be sufficient, but production bladesmiths benefit significantly from the extra capacity.
Is Peach State Pottery an authorized Paragon dealer for warranty coverage?
Yes, Peach State Pottery is an authorized Paragon dealer. Your one-year limited warranty from Paragon Industries is valid when purchased through us, but you must register your oven within 30 days of delivery. Warranty coverage is only valid through authorized dealers—purchasing from unauthorized resellers voids your warranty. We also provide ongoing technical support and can supply genuine Paragon replacement parts throughout the life of your oven.
