A shaver rasp has a small, curved blade. The body and handle are made of plastic, which is usually brightly coloured so as to decrease the chances of you loosing it.
As with pocket rasps and two-handled rasps, the blade of a shaver rasp allows it to be used on many other materials besides plasterboard. Shavings produced by the rasp are collected within the body, but as this is much smaller than on other rasps it will require more frequent emptying.
The fine teeth of the shaver rasp produce a smooth finish on the edge of plasterboard, but the small curved blade makes it less suitable for use on long, straight sections of plasterboard. Instead they are better suited for use on small cut-out sections of plasterboard and curved shapes.
