A slab and block splitter is a heavyweight specialist tool which is used to cut large blocks and slaps used for paving. Slab and block splitters generally consist of a heavyweight guilotine-style blade mechanism which is actuated by a large lever handle. When the handle is pulled down it exerts a massive amount of force onto the slab which splits it in two inline with the blade. The blade height of the tool is usually adjustable to compensate for materials of different thickness.

Slab and block splitters also come in hydraulic versions which takes some of the effort out of the work.
