Magnacut is the knife steel that changed the conversation. Developed by metallurgist Larrin Thomas and released in 2021, it was engineered from the ground up to solve the tradeoff problem that has plagued stainless steels for decades — exceptional corrosion resistance without sacrificing toughness or edge retention. The result is a steel that outperforms most premium stainless options across all three categories simultaneously. Makers and production houses adopted it quickly, and for good reason: Magnacut responds beautifully to heat treatment, takes a refined edge, and holds it under real use. If you're looking for a modern stainless that punches well above its weight, you're in the right place.
