A quarry rock splitter is someone who splits or separates blocks of rough stone from a quarry mass, using a jackhammer and wedges. It is a highly specialized job that is only done in stone quarries, which are a type of open-pit mine from which rock and minerals are extracted for use as building materials. For many people the idea of a rock quarry and someone breaking stone brings up visions of the cartoon character Fred Flintstone, who famously worked at Slate Construction.
