Many times, square and rectangle furniture tops have sharp corners. One takes “the points” off so it’s not a hard 90˚angle which can cause injury or chipping. This is called a blunt edge. “Tips off” or “points off” are other terms. You can hear “touched” edges – touching the edge to a grinding wheel.
A little larger amount of radius on the corners is called a “dime corner.” The glass is prepared so that the corners match the curvature of a dime. For bigger radiuses you can have a “nickel corner” or a “quarter corner.”
