Pointed-tip rock hammers, officially called rock picks, are used by geologist and rockhounds when working with "hard rock." Hard rock is, well, hard. Granitic, metamorphic, and sedimentary rocks are all part of the hard rock family.
Geologists and rockhounds use the square head of a rock hammer, or rock pick, to crack open a rock to see what the rock looks inside rather than the weathered outer surface of the rock, which often appears totally different than the real rock type.
Pick those gold collecting cracks and hard to dig areas with this recommended pick.
