Flat knife with cutting edge, used for wood cutting or cutting. The different parameters of the blade mounted on a variety of machine tools, can be processed in different ways, such as slicing, peeling, scraping and shearing. Slicing is used for plane machining, and the blade or workpiece generally makes a linear motion. To cut thin wood under certain conditions (such as reducing the cutting angle), thin wood is a high-quality decorative material. During peeling, the wood rotates around a fixed center and the blade performs a continuous linear motion toward the center, cutting the wood into strips of thin wood (single board) for the production of plywood. Shears are used to cut veneers when producing plywood.
