Bush hammer
Hammer with an elongated hammer head (approx. 10-20 cm long, approx. 2-5 cm
wide) made of hardened steel with pyramid-shaped pointed teeth on both
faces and a wooden handle (approx. 30-40 cm), for flattening natural stone.
This type of stone finishing is called bushing. From the 17th century
onwards, the bush hammer was used for hard stone types, never for soft
stone or marble. Because the tips wear out quickly, there are models with
interchangeable heads. The disadvantage of this tool is that it sometimes
causes cracks that make the stone weather faster. See also the bouchard
(chisel). [MOT]
