A geologist's hammer, also known as rock hammer, rock pick, geological pick, or geo pick, is a specialized hammer used for splitting and breaking rocks. In field geology, it is employed to expose fresh rock surfaces, as weathered surfaces may obscure accurate analysis of a rock's composition, bedding orientation, mineralogy, history, and strength. In fossil and mineral collecting, geologist's hammers are used to break rocks in order to reveal specimens contained within.
