When too much plating builds up on a sharp edge, the result can be a brittle layer that easily breaks. Most manufacturers correct for sharp edges by grinding and deburring the edge until it is gentler. A common rule of thumb is to round off all edges until their radius is between 0.4 and 0.8 millimeters. 4. Cleavage Points
