Beryllium-copper wrench. Copper does not create sparks when you strike it against steel, an important fact if that steel is located on something like an oil well or other location where flammable gases are likely to be around. Unfortunately straight copper is not strong enough to make tools out of, so beryllium is added to greatly harden the alloy. This is an ordinary crescent wrench made of such an alloy by the Berylco company.
