The slanted or rounded edge between the bottom of a wafer and the side of a wafer is the bevel region. Beveling is achieved by edge grinding, or pressing the edge of a grooved grinding wheel against the wafer as it rotates. Beveling wafers can help to prevent chipping and can have an impact on the function of the semiconductor when it is finished.

This is where one of the biggest problems begins. a "grinder" style sharpening machine will absolutely ruin the Japanese style shear by destroying the convex edge and replacing it with a bevel "concave" edge. A convex grinding wheel can only make a concave edge on the shear blade. Don''t let anyone try to tell you different.
