Knife
Knife is a tool used to cut an object. Knives have been used as tools and weapons since the Stone Age again. The knives consist of two main parts, namely blade blades and handles or knives. Blades are made of flat metal with sharp edges; This sharp edge is called the blade. The handle of the blade is generally shaped elongated to be grasped by hand. The general shape of the knife is similar to the sword, the difference is that the sword blade is longer than the blade. When the blade is too small to cut something, a saw or ax is probably needed.
