The design of this traditional-style stone hammer is nearly as old as the trade of stonemasonry itself, and offers an efficient method for shaping stone. The blade can be used for splitting stone with the grain or along bed lines, while the flat, squared back of the hammer is used for trimming and general shaping.

The entire hammer has been hardened for maximum durability and should only be used to strike stone. The Mash Hammer should never be used to strike or be stuck by other tools. The 2lb, 3lb, and 4lb Mash Hammers are manufactured with carbide-tipped blades for increased wear resistance.
