It is a knife or folding knife that has a U-shaped blade tip that is usually ground on the outside. It is shaped similar to a resin plane . In the 19th century as a ripper and a crooked sharp knife was called, which was attached to a long pole and tearing of softwood brushwood served.
This blade can be used to make channel-like markings on trees (e.g. to mark their harvest, usually with an "X", or to attach a joinery mark to timber for half-timbered construction or roofing ). In the past, markings were attached to trees with the ripping hook, which indicated the location of the next nest box . In forestry, the tearing hook has largely been replaced by color markings, but is still used for cutting timber .
