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 "See your delivered price" above the Add to cart button to see freight and your delivered total.

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 — KM45 Pro KM45 Pro · 240V · Space-Age Ceramic Fiber · Large Capacity · 2350°F Max Professional-grade knife heat treating oven engineered for bladesmiths who demand precise temperature control and rapid heating cycles for consistent, repeatable results. Space-age ceramic fiber construction reaches 500°F in minutes, dramatically reducing wait times and allowing you to heat treat blades on-demand without outsourcing. Maximum temperature of 2350°F provides the heat range needed for hardening, tempering, and annealing across all knife 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 KM45 Pro?
The KM45 Pro reaches 2350°F, which accommodates virtually all knife steels including high-carbon steels (1095, 1084, 5160), tool steels (O1, A2, D2), and stainless steels (440C, AEB-L, 154CM). This temperature range covers hardening, tempering, annealing, and normalizing cycles for both simple carbon steels and advanced powder metallurgy alloys. The digital controller allows you to program precise ramp rates and soak times critical for different steel chemistries.
Do I need a gas inlet port for atmosphere control?
Most bladesmiths heat treat successfully in the standard KM45 Pro without atmosphere control, especially when using anti-scale compounds or foil wrapping. However, the optional gas inlet port allows you to introduce inert gases (argon, nitrogen) or controlled atmospheres to minimize oxidation and decarburization on finished blades or when working with reactive steels. This is particularly valuable for stainless steels or when producing bright-finish blades that require minimal cleanup.
What controller comes standard and how does it work?
The KM45 Pro includes a professional digital controller with programmable ramp/hold capability, allowing you to create multi-segment heat treating cycles. You can program heating rates (ramp), target temperatures, and hold times (soak) for each stage of your process—critical for proper austenitizing, stress relief, and tempering. The controller maintains precise temperature accuracy throughout the cycle and alerts you when complete.
How does the KM45 Pro compare to other Paragon knife ovens?
The KM45 Pro is Paragon's large-capacity professional model, designed for bladesmiths running production shops or heat treating multiple blades per cycle. The ceramic fiber construction provides faster heating than brick-lined models and dramatically reduced energy costs. If you're a hobbyist or occasional maker, consider a smaller Paragon knife oven. If you need even larger capacity or three-phase power, ask about Paragon's industrial heat treating ovens.
Why buy from an authorized Paragon dealer?
Paragon's warranty is only valid when purchased through authorized dealers like Peach State Pottery. Authorized dealers provide proper setup guidance, electrical specifications, technical support, and warranty service. We stock replacement parts, can recommend heat treating accessories, and provide ongoing support for your specific steel types and blade designs. Purchasing from unauthorized sellers voids your warranty and leaves you without factory-backed support.
