A knife is a tool used to cut an object. The knife consists of two main parts, namely the knife and the handle or the handle of the knife. The blade bar is made of flat metal with sharp edges; This sharp edge is called a knife. The knife handle is generally elongated so that it can be held by hand.
The general shape of a knife is similar to a sword, the difference is that the sword is longer than the blade.
If the knife is too small to cut something, a saw or ax may be needed.
