The hilt (rarely called a haft or shaft) of a knife, dagger, sword, or bayonet is its handle, consisting of a guard, grip and pommel. The guard may contain a crossguard or quillons. A tassel or sword knot may be attached to the guard or pommel.

The pommel (Anglo-Norman pomel "little apple") is an enlarged fitting at the top of the handle. They were originally developed to prevent the sword from slipping from the hand.

The grip is the handle of the sword. It is usually made of wood or metal and often covered with shagreen (untanned tough leather or shark skin).

The guard is just above the grip. It is a common misconception that the cross-guard protects the wielder's entire hand from the opposing sword.
