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 Maker Paragon Knife Oven - KM9 Pro KM9 Pro · 240V · 9" chamber depth · Ceramic fiber construction · 2350°F max Professional knife heat treating oven engineered for blade makers who want complete control over their heat treating process without relying on external services. The 9-inch chamber depth accommodates most blade lengths, while space-age ceramic fiber construction reaches 500°F in minutes—dramatically faster than traditional brick kilns. Precision temperature control up to 2350°F ensures proper hardening, tempering, and annealing for carbon and tool steels.
Max temperature2350°F
Chamber depth9 inches

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 most common knife steels including 1084, 1095, 5160, O1, and other carbon and low-alloy tool steels. It handles hardening and tempering cycles for these steels effectively. However, it does not reach temperatures required for high-speed steels or some stainless steels like CPM-154 or S30V, which require temperatures above 2350°F. Always consult your steel manufacturer's specifications for proper heat treating temperatures.
Do I need a gas inlet port for atmosphere control?
Most knife makers successfully heat treat in ambient atmosphere without gas inlet modification. The standard KM9 Pro works well for straightforward hardening and tempering cycles. However, if you're working with steels sensitive to oxidation or decarburization, or if you want to experiment with protective atmospheres like argon or nitrogen, you can add an optional gas inlet port. This is more common for production knife makers or those working with reactive steels.
What controller comes standard with the KM9 Pro?
The KM9 Pro includes a digital temperature controller with ramp/hold programming capability, allowing you to create multi-step heat treating cycles. You can program specific temperature ramps, soak times, and cooling rates essential for proper blade hardening and tempering. For advanced features like touchscreen control, graphing, and unlimited program storage, consider upgrading to the Genesis touchscreen controller.
How does the KM9 Pro compare to other Paragon knife ovens?
The KM9 Pro features a 9-inch chamber depth suitable for most blade lengths. Paragon offers other knife oven models with different chamber sizes and maximum temperatures. The "Pro" designation indicates this model includes advanced programming capabilities and ceramic fiber construction for rapid heat-up. If you work with longer blades or need higher temperatures for stainless steels, ask us about other Paragon knife oven models.
Why does it matter that I buy from an authorized dealer?
Paragon's one-year warranty is only valid when purchased through authorized dealers like Peach State Pottery. Unauthorized sellers cannot provide valid warranties, and Paragon will not honor warranty claims on kilns purchased through unauthorized channels. As an authorized dealer, we provide proper warranty registration, technical support, and access to Paragon's parts and service network.
