The main handle of a two-handled dry wall rasp is the larger handle and it is grasped with your dominant hand when in use. The main handle will be held differently depending on what type of two-handled dry wall rasp you are using. The flat file type is held as you would a flat file, while the plane type is held as you would hold a plane.
Second handle
The second handle of a two-handled dry wall rasp is the smaller of the two handles. The palm of your non-dominant hand is rested on the second handle and used to guide it during use.
Body
The body is the main part of the rasp and is where plaster dust and shavings are collected as you use it. The large opening at the top of the body allows the collected plaster dust and shaving to be emptied into a bin to reduce mess where you are working.
Blade
The blade is located on the underside of the body and is much longer than on other dry wall rasps. This means fewer strokes are needed to resize plasterboard, saving you time. However, the large size can prevent this type of dry wall rasp from being used in smaller, intricate areas such as cut outs around sockets.
