摘要

The slate hammer has a hammer handle (2). The hammer handle is aligned with hammer axis. At one end of handle hammer head (3) exists and at other end grip element (6) exists whereby surfaces (10,11) on hammer handle makes angle alpha /beta less than 90[deg] with cutting edges. The hammer has two cutting edges (12,13). The value of alpha /beta lies between 20[deg] to 40[deg] but preferred value is between 25[deg] to 35[deg].
