Misen is a kitchenware company built by self-described cookware obsessives, making pans and knives for everyday cooking. Its signature Carbon Nonstick™ line uses nitrided carbon steel rather than a chemical coating, aiming for naturally nonstick performance without PFAS, PTFE or PFOA. The company also offers mail-in sharpening for knives from any brand, with factory-grade restoration and optional loaners.
