A cutter knife, also commonly called a carving knife or wallpaper knife, is a knife used for art and handicrafts. It is mainly used to cut soft materials and usually consists of a plastic handle and a blade, with a pull-out design. A few have metal handles. The blade is usually beveled; when dull, it can be broken along the lines on the blade to create a new edge for easier use. Cutter knives come in various sizes.
When using a utility knife, usually only the tip is used; cutting, carving, and marking are its primary functions. Because the blade is quite brittle, it shouldn't be extended too far. Furthermore, the blade's hardness and durability (these are two different concepts in utility knives) vary depending on the blade's material. The handle should also be chosen according to hand shape, and instructions on how to hold the knife are usually provided on the back of the packaging.
