Abstract
The utility model discloses a folding knife cutting head and a folding knife, and belongs to manual tools. The folding knife cutting head and the folding knife solve the problems that an existing cutting body main body is larger in thickness and is difficult to stretch into smaller gaps to conduct cutting due to the fact that the cutting head main body is of an integrated structure when the cutting body main body is used, materials are wasted, and processing cost is higher. According to the folding knife cutting head and the folding knife, the main body is formed by stacking at least three layers of sheet materials and a blade lock is assembled on the main body. The thickness of a middle-layer sheet material is equal to that of a blade. A blade placing position is formed on the middle-layer sheet material, and the sheet materials on the two sides of the middle-layer sheet material cover the two sides of the blade placing position respectively. According to the folding knife cutting head and the folding knife, the sheet materials are cut and then stacked and tightened to form the cutting head main body, so that the thickness of the cutting head is reduced, the cutting head can stretch into smaller gaps to conducting cutting when the cutting head is used, manufacturing material consumption is reduced, and processing cost is reduced.
