Diamond is very hard, but hard materials also tend to be brittle. You can scratch a hammer with a diamond, which demonstrates that diamond is harder than steel. However, if you hit the diamond with the hammer in the right fashion, the diamond would likely break. Since diamonds are very hard to cut, special diamond bladed edges are used to cut them. Diamonds are prepared using several different cutting and forming methods. They can be broken along natural planes of weakness in the the crystalline structure using a hammer and steel chisel. A diamond or laser can be used to make a scratch on the diamond, which is then broken with a hammer and steel chisel - a concept not unlike cutting glass. Saw blades impregnated with diamond dust on the cutting edge and lasers can also be used to cut a diamond. Diamond powder is used to polish diamonds.
