Hammer is a tool consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. Hammers are used for a wide range of driving, shaping, and breaking applications.

The hammer grinding surface is painted, and a variety of colors can be selected, i.e. rust removal, and the appearance is beautiful and generous.

The surface shall be treated with high-grade anti rust oil to avoid rusting.
