...-effective. Shears Shears are normally used to prepare large, relatively thin materials (≤25 mm, or 1 in., thick) by cutting them to final dimensions. The two principal shearing variations are straight-knife shearing and rotary shearing. In straight-knife shearing, the work metal is placed between...
