A Nail Clipper is a two-part tool

Generally, a nail clipper is a two-part tool, comprising a blade body and a supporting shaft. The blade body can be made in one piece or by spot welding. The supporting shaft passes through the blade body and is connected to the upper blade.The blade body is shaped like an arc. The upper blade is called a "lap" and the lower blade is called a "blade". The blade body is fixed on the supporting shaft with the angle of 43 degrees.

The blade body has a curved surface which is matched with the curved surface of the edge end. In order to make the curved surface match the curved surface of the edge end, a grinding roller is attached to the blade body. The grinding roller has the diameter of the curved surface of the edge end.The arc type blades of the nail clipper are formed by grinding top and bottom edges at the same time. The top and bottom edges are then sharpened. The grinding depth can be varied. The grinding depth depends on the abrasion of the grinding belt and the variation of the transfer unit.

The arc type blades of a nail clipper are a special feature. The blades can be formed in one body by bending or spot welding. In order to make the blade body, the upper and bottom blades are displaced by an amount of 0.1 mm. This amount of displacement is extremely subtle and requires a great deal of skill on the part of the operator.
