The 18-inch chamber depth accommodates everything from pocket knife blades to full-size chef's knives and machetes. For extremely high-alloy powder metallurgy steels requiring temperatures above 2100°F, verify your specific steel's heat treating requirements against the maximum 2350°F rating.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eDo I need a gas inlet port for atmosphere control?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe gas inlet port is optional but recommended for professional knifemakers concerned about surface oxidation and decarburization. It allows you to introduce nitrogen, argon, or other protective atmosphere gases during the hardening cycle, which is especially important for stainless steels and when you want to minimize post-heat-treat grinding. For basic heat treating of high-carbon steels where you'll grind the blade afterward, the standard configuration without atmosphere control works perfectly fine.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eWhat controller comes standard with the KM18?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe KM18 includes a digital programmable controller as standard equipment with adjustable temperature settings and basic ramp\/hold programming. This controller provides accurate temperature control for straightforward hardening and tempering cycles. For advanced knifemakers who want multi-segment programs, data logging, and touchscreen operation, the Genesis controller upgrade is available and provides significantly more programming flexibility for complex heat treating recipes.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eHow does the KM18 compare to smaller knife ovens?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe KM18's 18-inch chamber depth is the key differentiator—it handles full-size blades that won't fit in 12-inch or 14-inch models. If you're making large bowies, swords, machetes, or chef's knives over 14 inches, the KM18 is necessary. For makers focused on folders, small fixed blades, or EDC knives under 12 inches, a smaller model may be more economical and heat up faster. The KM18 also accommodates batch processing of multiple smaller blades simultaneously.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eIs this kiln covered under warranty if I buy from Peach State Pottery?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes. Peach State Pottery is an authorized Paragon dealer, which means your KM18 is covered by Paragon's full one-year limited warranty on parts and workmanship. You must register the furnace within 30 days of delivery directly with Paragon. Purchasing from an unauthorized dealer voids the manufacturer warranty, so always verify dealer authorization before buying heat treating equipment.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"d-cta\"\u003e\n  \u003cdiv\u003e\n    \u003cspan class=\"d-cta-title\"\u003eNot sure if the KM18 is the right furnace for your blades?\u003c\/span\u003e\n    \u003cspan class=\"d-cta-sub\"\u003eOur team can help you compare chamber sizes, discuss your steel types, and recommend the right heat treating setup for your knifemaking operation.\u003c\/span\u003e\n  \u003c\/div\u003e\n  \u003ca href=\"https:\/\/peachstatepottery.com\/pages\/contact-us\" class=\"d-cta-link\"\u003eTalk to an expert →\u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Paragon","offers":[{"title":"Blue","offer_id":48584627191963,"sku":"KM18-BLUE","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Berry","offer_id":48584627224731,"sku":"KM18-BERRY","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Sea Glass","offer_id":48584627257499,"sku":"KM18-SEAGLA","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Navy","offer_id":48584627290267,"sku":"KM18-NAVY","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Hot Pink","offer_id":48584627323035,"sku":"KM18-HOTPIN","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Turquoise","offer_id":48584627355803,"sku":"KM18-TURQUO","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Jade","offer_id":48584627388571,"sku":"KM18-JADE","price":3932.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":48584627421339,"sku":"KM18-BLACK","price":3932.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7160\/9243\/files\/product-image-1_77c3ceca-0503-4264-b332-b86a8914e353.jpg?v=1778962914","url":"https:\/\/peachstatepottery.com\/products\/paragon-knife-oven-km18-heat-treating-furnace","provider":"Peach State Pottery","version":"1.0","type":"link"}
