A bush hammer, also known as an axe hammer, is a masonry tool used to texturize stone and concrete. The term is derived from the German word bosshammer, where Old German bossen meant "to beat".
Bush hammers exist in many forms, from simple hand-held hammers to large electric machines, but the basic functional property of the tool is always the same – a grid of conical or pyramidal points at the end of a large metal slug. The repeated impact of these points into stone or concrete creates a rough, pockmarked texture that resembles naturally weathered rock. They can help to increase bonding effectiveness when applying new concrete to an existing concrete surface by increasing the surface area of the bonding zone.
The bush hammer has been modernized, making it easier for the users to perform tasks while still producing the intended effect. Powered machines are built to give the impression that a hand-powered bush hammer has been applied to the concrete. This allows contractors to work on a larger amount of the material without using individual hammers for the project. This saves time and labor costs for those working with the tool. There are angled points that rotate to help imitate this tool.
The bush hammer is the patented title for this tool but has also been called different names over the years. The other most common name was the patent hammer which is described to have the same features and was used around the same time of the bush hammer. Another name this tool can go by is the axe hammer. This is due to the sharp conical edges the face of the hammer would contain.

Bush hammering is a method of texturing concrete the same way it is done with natural stone. Natural stone can be bush hammered with either bush hammer rolls or a percussive hammer when concrete is only hammered with rolls.
It thus provides an authentic look to outside new or refurbished concrete projects. In addition to bringing the gritty aesthetic side to concrete slabs, it also has useful anti-slippery properties in urban areas or for stairs. New alternative to exposed aggregate concrete or sand blasting, bush hammers also offers many advantages: no use of toxic products, no use of water, little amount of dust (thus limiting the inconvenience to nearby businesses, for example), no heavy lifting and few handling, bush hammers systems being directly fitted onto traditional machinery.
