A handheld tool similar to a hammer or a pickaxe, intended for use by geologists to remove samples of rock. A geology pick will have a handle like that of a hammer, but the handle might be a little bit longer than a normal hammer. The business end is made of steel and has two parts, each perpendicular to the handle and facing away from each other: one tapers to a point for rooting around and prying, and the other has a flat face for striking. In the geology picks I've seen, the striking surface has a square cross-section.
