For other uses, see Knife (disambiguation)

A knife is a sharp-edged hand tool used for cutting. A knife usually consists of a blade attached to a handle. The blade of a knife is usually pointed and may have one or more cutting edges. Knives have been used as tools and weapons since the Stone Age, in the dawn of humanity. Specialists recognize the knife as one of the first tools designed by the man in order to survive.

The first knives were flint or other rock, chipped or ground to an edge, sometimes with a handle. Later on with advances in smelting and metallurgy the blades were made of bronze, iron, then steel. While the materials have changed over time, the basic design remains the same.
