Oblique knife: The knife edge is at a bevel angle of about 45 degrees. It is mainly used for corner cutting and polishing at the joint corners and hollow slits of the work. If you want to engrave the corner of a character's eyes, the oblique knife is better. The material knife is divided into forehand oblique and backhand oblique to suit all directions. Yuwan Knife: It is not as straight as a flat knife, nor as deep as a round knife, so it is suitable for use on concave surfaces.

Zhonggang knives are also used to engrave patterns and patterns on character clothing and props.
