Kiln Controller
A digital controller in its own wall-mounted box. It runs the kiln through a power cord, away from the kiln's heat.
Who needs it: Kilns with a manual or worn-out controller, or studios that want a different interface. Pick the voltage and amperage that match your kiln.
Skip it if this kiln already has a programmable controller built in. Most buyers do not need a second one; ask us about the factory touchscreen upgrade instead.

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, 20 amps, with a NEMA 6-30 receptacle. 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 Kiln
Paragon Double Barrel KM14 Pro Knife Oven
The Double Barrel KM14 Pro features one extra-wide firing chamber with 2-zone control that lets you heat treat more blades in a single load, dramatically increasing production capacity for professional knifemakers. Ultra-fast heat-up capability reaches 500°F in minutes thanks to space-age ceramic fiber construction, reducing wait times and maximizing throughput. Built in the USA with precision engineering for repeatable hardening and tempering cycles across high-carbon, tool steels, and stainless alloys.
Max Temperature2350°F
Chamber ConfigurationOne 13.25" W × 5.25" H × 14.5" D chamber

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 KM14 Pro?
The 2350°F maximum temperature handles all common blade steels including high-carbon alloys (1095, 1084, 5160), tool steels (O1, A2, D2), and most stainless steels (440C, AEB-L, 154CM). For specialty steels requiring higher austenitizing temperatures like CPM S35VN or CPM M4 (typically 1900-2150°F), this oven provides adequate overhead. The extra-wide chamber lets you harden more blades per load, streamlining your workflow for production knifemaking.
Do I need the optional gas inlet for atmosphere control?
The gas inlet and flowmeter are an optional factory upgrade, but highly recommended for professional results. Running nitrogen or argon through the chamber during heat treating prevents oxidation and decarburization, eliminating scale formation and preserving surface carbon content for optimal edge performance. If you're working with high-alloy stainless steels or want bright, scale-free finishes, connecting an inert gas system significantly reduces post-heat-treat grinding and finishing time. You'll need a standard industrial gas regulator and appropriate hose fittings (available as accessories).
What controller comes standard and can it handle complex heat treat cycles?
The KM14 Pro Double Barrel includes one Sentinel touchscreen controller with 2-zone control and programmable ramp-hold capabilities, allowing you to create multi-step heat treat programs for precise austenitizing, soak times, and tempering cycles. Its front and rear thermocouples help keep the temperature even along the chamber. For advanced features like USB data logging or expanded program storage, you can upgrade to the Genesis touchscreen controller, which includes pre-programmed cycles for common knife steels.
How does the Double Barrel KM14 Pro compare to single-chamber knife ovens?
The Double Barrel keeps the 14.5-inch depth of the KM14 Pro but has a much wider chamber (13.25 inches), so you can load more blades side by side without needing additional electrical circuits or workspace. It is one chamber with one 2-zone controller, so everything in a load runs the same program; the two zones simply keep the temperature even from front to back. For full-time knifemakers or small production shops, the extra capacity typically pays for itself in increased throughput.
Is this purchase covered under warranty, and does it matter where I buy it?
Paragon provides a one-year limited warranty on the KM14 Pro, but warranty coverage is valid only when purchased through authorized dealers like Peach State Pottery. You must register your oven within 30 days of delivery to activate warranty protection. Purchasing from unauthorized sellers or third-party marketplaces typically voids manufacturer warranty coverage and may result in receiving older inventory, modified units, or lacking technical support from Paragon's heat treating specialists. As an authorized dealer, we ensure you receive current-production units with full factory support and can assist with warranty claims if issues arise.
