In shear slitting, blade profile is one of the most frequently asked questions. While slit-edge quality is the result of many factors, blade profile is one of the factors most frequently changed in an attempt to improve slit quality. Often, a profile change does not yield the expected results because the shearing mechanism itself is not well understood.

Gone are the days when a shear-slitting knifeholder was a primitive, cast-iron contraption that required a pocketful of wrenches every time a pattern change was made. It had to have the durability of an anvil because repositioning involved a lot of pounding with a hammer. Lost time, lost product and accidents were a fact of life. This, of course, is no longer acceptable.
