Blade materials are those used to make the blade of a knife or other simple edged hand tool or weapon, such as a hatchet or sword.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.Other less common materials used in knife blades include: cobalt and titanium alloys, ceramics, obsidian, and plastic.s 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). 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).
