SABRE SAW BAR AND BLADE HOLDER ABSTRACT In accordance with the present invention a motorized sabre saw for reciprocating an elongated saw blade, or the like, is provided with a saw bar and blade holder or chuck combination wherein an end portion of the saw bar is of gen- erally circular cylindrical configuration having a longi- tudinally extending groove therein having a first wall spaced apart from a radius of the bar a distance substan- tially equal to one-half the thickness of the blade to be driven thereby and generally parallel such radius and a second wall generally perpendicular the first wall extend- ing from the first wall across such radius with the first and second walls defining therebetween a generally square shoulder whereby a blade clamped thereagainst will be gen- erally bisected by such radius, together wth a clamp block mounted with the saw bar over at least a portion of such groove and having a first generally cylindrical aperture a major portion of which is generally circular and complemen- tary to the end portion of the saw bar and the remaining portion of the aperture comprising a generally rectangular groove, one wall of which is disposed in general alignment with the first wall of the saw bar and the opposite wall of the rectangular groove intersects the second wall of the saw bar generally perpendicular thereto with said one wall and said other wall being spaced apart a distance at least the thickness of the blade shank, together with first fastening means securing the clamp block with the saw bar and second fastening means replaceably securing the saw blade, or the like, within the aperture. The saw bar and the second fast- ening means are preferably fabricated with material such as steel which is capable of supporting the stresses induced by the reciprocating saw blade or the clamp block may be fabri- cated of a much lighter weight, low mass material, such as a magnesium.
