A power saw has a sword having side walls which form a groove-shaped guide, and two parallel oppositely reciprocable saw blades having one longitudinal side provided with saw teeth and another longitudinal side provided with backs which are guided in the groove-shaped guide. The groove-shaped guide is interrupted by a plurality of recesses.

A hand held power tool has a working disc and a working sheet held on the working disc by a burdock connection. The working disc has a burdock surface. An intermediate pad is held on the burdock surface of the grinding disc. The intermediate pad has a first side provided with a velour coating and releasably connectable with the burdock surface of the grinding working disc and a second side releasably connectable with the working sheet.

A motor driven hand circular saw has a base plate arranged to be positioned over a workpiece, and a saw blade which is displaceable parallel and tiltably about a turning axle relative to the base plate for performing inclined or bevel cuts so that by tilting of the saw blade relative to the base plate about the axle, the saw blade and the axle are displaced parallel to the base plate with a stroke which is proportional to a respective tilting angle transversely to a direction downstream of a cutting point and counteracts a natural displacement of a saw engaging line of the saw blade on the workpiece.
