Bush hammer

A bush hammer is a masonry tool used to texturize stone and concrete. 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.

gollark: Haskell meets 1 (obviously), 2, 3, kind of 5 and maaaybe 7.
gollark: - nice, nonbrackety haskell syntax- functional-programming-oriented- strongly typed- pragmatic and not horribly complicated - yes, selective applicative functors or whatever new haskell thing is now being worked on may be elegant, but learning every needlessly fancy thing just takes away from *actually writing useful stuff*- good tooling (see: Rust; run screaming from: Go, C(++))- web platform, ideally (yes, it has Problems™, but there's something to be said for ability to just navigate to a webpage and run your stuff- good libraries/community
