The caliper used outside the factory measures most of the claws with a knife edge. Due to the existence of the knife edge, it is not easy to flatten when measuring the flatness and parallelism of the claw outside the repairing grinding. When the two measuring surfaces are closed, there is a gap at the cutting edge. Some people change the grinder to small, and only grind the wide surface when grinding. The result is a slightly concave middle of the wide face, a slightly higher transition between the wide face and the edge, and only the contact at the transition when the two measuring faces are closed, flatness and parallel
