The following are tool steels, which are alloy steels commonly used to produce hardened cutting tools: Tool steel grades used in cutlery : A, D, O, M, T, S, L, W.
Laminating a harder steel between a softer one is an expensive process that to some extent gives the benefits of both types (see Damascus steel). As hardness increases, the blade becomes capable of taking and holding a better edge, but is more difficult to sharpen and more brittle (commonly called less "tough"). The Rockwell scale is a hardness scale based on the resistance to indentation of a material, as opposed to other scales such as the Mohs scale (scratch resistance) testing used in mineralogy. The hardness of steel is usually stated as a number on the Rockwell C scale (HRC). Other less-common materials used in knife blades include: cobalt and titanium alloys, ceramics, obsidian, and plastic. The blade of a knife can be made from a variety of materials, the most common being carbon steel, stainless steel, tool steel and alloy steel.
