1. A universal saw capable of being employed as a jigsaw or sabre saw, having a housing and a base plate (21) for supporting the universal saw on a work piece to be machined wherein:
the housing contains a drive train that includes an electric drive motor and a motion converter that converts a rotary motion of the drive motor into a reciprocating working motion of a saw blade movably guided in the housing, and
the base plate for supporting the universal saw on the work piece to be machined is linked to the housing (12) by means of two parallel pivot axes (24, 25) and
a distance of one of the pivot axes (25) from the housing (12), measured parallel to the reciprocating working motion of the saw blade (14,15), is constant, while a distance of the other pivot axis (24) is variably adjustable, but also is lockable in a definite, first operating position in which the two distances are equal;
when being employed as a saber saw, the base plate is arranged on the housing in a pivoting fashion wherein the pivot axis (25) that is spaced the constant distance apart from the housing (12) is situated in front of the saw blade (15), and the other pivot axis (24) with the variably adjustable distance from the housing (12) is situated behind the saw blade (15) and wherein:
on the one hand, the base plate (21) is rapidly lockable in the definite, first operating position in relation to the housing of the universal saw (10) in which position, the direction of the reciprocating working motion of the saw blade (14, 15) is perpendicular to the base plate (21) and
on the other hand, it is possible outside of this operating position, to variably adjust the angular position of the base plate (21) in relation to the direction of the reciprocating working motion of the saw blade.
