    Traditional Finnish puukko knife

    A knife is a sharp-edged hand tool used for cutting. A minimal knife is a blade and some method of gripping it. Knives have been used as tools and weapons since the Stone Age.

    The first known knives were flint or other rock, chipped or ground to an edge, sometimes with a handle. Palaeolithic knives may also have been made from wood, bone or antler, but these materials do not survive in the archaeological record. Advances in smelting and metallurgy have led to blades made of bronze, iron, then steel and more exotic materials. Both materials and designs have changed over time.

    All cultures use knives as tools. Together with the fork and spoon, the knife has been a ubiquitous eating and cooking utensil in the Western world since at least the Middle Ages. The importance of knives as weapons has declined, but knives are still made and carried for other purposes. The tang is an extension of the blade into the handle. The bolster usually helps to join the blade to the handle and adds greater strength. Some bolsters also may function as a barrier, or handguard, to prevent fingers from slipping onto the blade. A bolster with a definite extension away from the handle often serves as a guard to further protect the hand when using a knife.

    Common blade features include serrations, coatings, and functional or decorative embellishments, including engraving, opening holes, thumb studs, disks and nail grooves. A fuller, sometimes mistakenly called a blood gutter or blood groove, is a depression along a blade. There is a myth that this promotes bleeding from stabbing wounds. The actual function is to lighten the blade without sacrificing stiffness, and on many knives it is purely decorative.

    Some knives have a choil where the blade is unsharpened and possibly indented as it meets the handle. A small choil is used to prevent scratches to the handle when sharpening the blade, while a large choil is useful as a forward-finger grip. Handles may be made of any solid material: wood, steel and decorative materials are common. ..."
