A cutting tool used to make complex straight and curved cuts in sheet metal, that looks like a long pair of scissors. Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. The 2 blade types for shear cut blades consist of flat blades and dished blades.
