A set of 30 spare blades made of high-quality steel, curved at an acute angle. These blades are ideal for cutting and scoring materials such as cardboard, plastics, wax, cork, softwood (including balsa), and dried modeling clay. Together with a suitable modeling knife, they prove very useful for working with plastic models, and with a certain amount of skill, they can be used for creating or deepening sheet metal parting lines, for example, in model airplanes or helicopters. They can also be successfully used for cutting modeling tape. It's worth noting that the set also includes a special plastic case with a very simple closure, allowing for safe disposal of used blades.
