AUS-10 is one of the more interesting stainless steels coming out of Japan - a high-carbon alloy from Aichi Steel in Tokai with added nickel, manganese, silicon, vanadium, chromium, and molybdenum that give it superior corrosion resistance, improved ductility, and a finer edge than most stainless alternatives. Tsunehisa builds their AUS10 line around it in Tosa, Japan, cladding the core in stainless and finishing the blade road with a hammered Damascus pattern and a striking mirror polish. The result is a knife that looks considerably more expensive than it is.
As a Japanese steak knife this one stands apart from the typical Western table knife in every meaningful way - thinner behind the edge, harder steel, and a distal taper that gives it a laser-like feel on the plate. At 83mm blade length and only 2mm spine thickness, it glides through protein with minimal resistance. The blue handle is a standout at the table. Sold individually so you can build a set to your own preference or add a single knife to an existing collection.
Care Instructions: AUS-10 is a stainless steel - low maintenance and resistant to corrosion. Hand wash and dry after use. Avoid the dishwasher, bones, and frozen foods. Sharpen on quality water stones when needed.
