The hammerhead of the fitter hammer has two directions. It has always been a round head, which is generally used to strike rivets, and the other has always been close to a flat head, which is generally used to strike the more flat surface.  The flat end is generally used for striking, and the pointed end is used for sheet metal.  The fitter’s hammer is used when we decorate a house to reinforce objects by hitting nails on a flat surface.

The fitter hammer also has another end, which is the pointed part and is used for auto sheet metal

• The hammer is metal in the middle and hard or soft plastic at the ends
