摘要：

The secateurs (1) have a movable upper shear blade (3) and a fixed lower shear blade (4), where the blades are formed with curved edges (14,15) and back edges (16,17). The curved edges and the back edge take the shape of a blade with closed back when the secateurs are locked. The curved edges have saw-tooth structures (19,20) to use the secateurs as rake.
