What is a blanked shear?
Most less expensive shears are blanked out. Strips of steel are cut out in the form of a shear, like rolled cookie dough is shaped with cookie cutters. The cheaper version of the “Blanked” shears are then ground into shape. For a better quality the cut out “Blanks” are put into a powerful press and the blade is squeezed into shape. Thereby the steel near the edge is compressed and the cutting edges last longer. This means that not all cheaper shears are equally cheap. Drop forged tools and shears are far superior to blanked ones. The material flow of the hot metal being forged and pounded into the cavity gives the steel a much denser structure, better quality and ultimately longer life.
