Scrapers may more accurately described at cutting tools as the edge is "turned up" with a hard steel rod (burnisher) to form a burr or hook which cuts into the wood to produce a fine shaving (just like a very finely set spokeshave or plane). Scrapers are used as the final cleaning up operation on hardwoods, especially cross grained or highly figured timber.
They can be shaped for convex or concave work or square. They are marvellous tools and are inexpensive additions to your tool armoury.
Scrapers can be hand held or in a holder or fixed into a metal or wooden plane or spokeshave body (see plane section).
