Experience provides a more suitable length to hold the hammer. The length of the head and forearm is equal to the length of the hand hammer; hand swing can be used when the hitting force is small, and the arm should be swing when the hitting force is large; when using the swing arm, it should be noted that the movement arc of the hammer head and the hammer handle should not be contaminated by grease.
