Kitchen Knife Steel Explained

Steel affects corrosion resistance, toughness, wear resistance and sharpening behavior, but the steel name is only part of the story.

Heat treatment and blade geometry can matter as much as alloy designation. Two knives using similarly named steel can perform differently.

What matters most

Treat “Japanese steel” or “German steel” as incomplete descriptions unless an actual alloy and treatment are specified.
