Grind (skateboarding)

Grinding is damaging to materials which are not hardened for the specific purpose of the sport, as may be found in a skate park.

Grinding can strip paint off of steel and wear down the edges of concrete, stone, aluminum, and wood building materials.

Affected business owners and government buildings have put up anti-skate devices as a deterrent to grinding.

[2] Grinding in public places may be seen as a form of vandalism and may cause skateboarding to be banned by business owners and city ordinances.

[3] Whether a grind is back-side (BS) or front-side (FS) depends on how rider approaches the rail or edge.
