Hammer is most commonly used to knock nails, correct or open objects. There are many forms of hammer. The common form is a handle and a top. One side of the top is flat for knocking, and the other side is a hammer. The hammer can be angular or wedge-shaped, and its function is to pull nails. In addition, it has a round-headed hammer. The weight of the hammer should be suitable for the workpiece, material and function. Too heavy or too light will be unsafe.
When using a hand hammer, pay attention to the connection between the hammer head and the hammer handle. If it is slightly loose, wedge or replace the hammer handle immediately. The handle length of the hammer must be moderate. Experience dictates that the appropriate length is to hold the hammer, and the length of the forearm is equal to the length of the hammer.
Type of hammer
Round-headed hammer is one of the most common kinds of hammer, which has flat head and round head and is usually used for metal forming. Claw hammer is one of the most common hammers, because one end of the hammer is famous for its claw shape. The shape of claw head is very suitable for nailing, so it is quite popular in woodworking industry. Impact hammers are mainly used in buildings, such as tearing down walls and breaking cement. Therefore, both the length of the handle and the weight of the head are far ahead of all hammers, and the percussion hammer usually needs two hands to operate.
Stone hammer is similar to percussion hammer, and its hammer head and striking surface are larger than ordinary hammer, which can be regarded as compact percussion hammer. This design is more suitable for the operation of cutting masonry with chisel, hence the name. The extended handle hammer is similar to the claw hammer, but the handle ratio is longer, so it may get better leverage. Because of this feature, some hammers also have a place to put nails at the front end, which is convenient for nailing nails directly into the wood.
