ABSTRACT:
A rotatable portable saw has a saw blade 2 which is pivotally mounted with respect to plate 15 so that the position of the blade relative to the plate 15 can be altered to alter the depth of cut. In a modified form the saw blade can be angled slightly to the direction of traverse of the saw so that the width of the cut can be made slightly greater than the width of the blade. In use the saw is traversed across a workpiece with the blade positioned to produce a scribing cut in the surface of the workpiece and then traversed back across the workpiece, after lowering the blade position relative to the workpiece, so that the workpiece is cut right through. In this way, for a given directional rotation of the blade, the blade can be made always to approach the surface being cut so that splintering of the workpiece is substantially reduced or eliminated. With the modified form of saw the blade is angled so that the scribing cut is made slightly wider than the saw blade and the blade is realigned at the end of the first traverse with the direction of traverse so that on the reverse traverse the saw blade emerges in the wider cut reducing still further any chance of splintering.
