1. An electric hand tool comprising, a housing, a reciprocating carrier for an operating member having an elongated, generally rectilinear working edge, said carrier being drivable by means of an electric motor contained in the housing for reciprocating the operating member along a generally rectilinear axis parallel to said working edge, forward and rearward guide assemblies supporting the carrier for generally reciprocal movement, each guide assembly having upper and lower rollers respectively engaging upper and lower planar surfaces of forward and rearward sets of such surfaces formed on the carrier, said planar surfaces being contained in parallel planes which are perpendicular to a plane containing the working edge of the operating member, each guide assembly having one of its rollers mounted for movement to and from the adjacent planar surface of the carrier, each guide assembly including spring means for urging said one roller into engagement with the carrier, and a sub-frame mounted in the tool housing and in turn mounting one of the guide assemblies for reciprocal movement in a plane generally perpendicular to the axis of reciprocation of the operating member.
