Paragon Knife Oven – KM24
Professional knife heat treating oven engineered specifically for blade makers, featuring a 24-inch deep chamber that accommodates multiple blades or longer knives in a single firing cycle. Reaches a maximum temperature of 2350°F for proper heat treating, hardening, and tempering of high-carbon steels and tool steels commonly used in blade making. Available in both 120V and 240V configurations with standard or advanced controller options to match your workshop requirements.

Common questions
What types of steel can I heat treat in the KM24?
The KM24 reaches 2350°F, making it suitable for heat treating high-carbon steels (1095, 1084, 1075), tool steels (O1, A2, D2), and most popular knife-making steels. This temperature range covers austenitizing temperatures for hardening as well as lower tempering ranges. Stainless steels requiring higher temperatures (like 440C or S30V) may need specialized equipment, but the KM24 handles the vast majority of carbon and alloy steels used by custom knife makers.
Do I need a gas inlet port for atmosphere control?
A gas inlet port is optional but recommended for professional knife makers concerned with oxidation and decarburization. The optional atmosphere port allows you to introduce inert gases like argon or nitrogen, or use specialized atmosphere-control systems to protect blade surfaces during heat treating. Many makers successfully heat treat without atmosphere control by using foil wraps or anti-scale compounds, but a controlled atmosphere provides the cleanest results and eliminates surface grinding.
What controller comes standard, and are upgrades available?
The KM24 comes standard with a digital controller that offers programmable ramp/hold segments for creating precise heat treating cycles. This allows you to program specific heating rates, soak times, and cooling protocols essential for proper heat treatment. An advanced controller upgrade is available, offering additional programming segments, enhanced accuracy, and more sophisticated control features for knife makers running complex or experimental heat treating schedules.
How does the KM24 compare to other Paragon knife ovens?
The KM24's defining feature is its 24-inch chamber depth, which accommodates longer blades like swords, machetes, and oversized chef knives, or allows batch processing of multiple smaller blades. Smaller Paragon knife ovens offer similar temperature ranges and capabilities but with shorter chambers suited for standard knife lengths. The KM24 is ideal for makers who regularly work with longer blades or need higher production capacity in a single firing cycle.
Can I purchase this oven through any dealer, and how does warranty work?
Paragon warranties are only valid when purchased through authorized dealers like Peach State Pottery. Purchasing from unauthorized sellers or second-hand sources typically voids manufacturer warranty coverage. You must register your oven within 30 days of delivery to activate the one-year limited warranty. As an authorized Paragon dealer, Peach State Pottery provides full warranty support, technical assistance, and access to genuine replacement parts throughout your oven's lifetime.
