Hitohira Hinode Kurouchi Nashiji White #2 Stainless Clad Sujihiki 210mm Ho Wood Handle

This is a carbon steel knife with a soft stainless steel cladding. Most Japanese knives have a 3-layer construction called “San Mai”, hard and high quality steel sandwiched between two layers of soft steel. In this case the soft steel (cladding) is a stainless steel and only the core is made out of carbon (non-stainless) steel. You’ll have all the advantages of a carbon edge e.g., sharpening ease and edge retention, but without having to worry about oxidation on the rest of the blade.
Still it is important to store your knife dry and clean, never let it air-dry after washing, no dishwasher and avoid extremely hard products like frozen foods or bones ect.
