Scutch hammer is described by its type: single scutch and double scutch. Similar in shape to the brick hammer. The single scutch hammer has one striking face like the brick hammer, while on the other end of the head a groove is cut to take either scutch combs or chisels. These bits are replaceable and are used for cutting stone or brickwork or for removing mortar from brickwork prior to re-pointing. The double scutch has no striking face, but is grooved at both ends.
