A knife is a sharp-edged hand tool used for cutting. A knife usually consists of a blade, usually less than 12 inches (30cm) in length, attached to a handle. The blade of a knife is usually pointed and may have one or two cutting edges. Knives have been used as tools and weapons since the Stone Age.

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.

Together with the fork and spoon, the knife has been a common eating utensil in the West since the Middle Ages. In the West, multi-purpose pocket knives are probably the most common knives carried today, and the importance of the knife as a weapon is declining.
