Art knives are used for cutting. Also known as a carving knife or wallpaper knife. When the art knife is used normally, it only uses the tip part. Cutting, carving and dotting are the main functions. However, this kind of blade is very fragile and cannot stretch out too long when used. In addition, the hardness and durability of the blade (these are two concepts in the art knife) also differ due to the different texture of the blade.
