An angularly reciprocating pivotable yoke, driven by a motor or a power t, is attached to respective ends of an abrasive coated cable or wire blade to draw the blade back and forth over a workpiece and provide cutting thereof, particularly in close quarters where little clearance is provided adjacent a workpiece. A telescoping housing includes a movable protective cover for protection of both the user and the mechanism. A safety switch is provided for preventing operation of the mechanism when the protective cover does not cover moving parts of the mechanism. A pivotable support for attachment of the ends of the blade to ends of the pivotable yoke is preferably of cylindrical form and which has a slotted aperture for receiving the blade and a recess for receiving an enlarged blade end, preferably formed by a piece of tubing crimped to the blade. The cylindrical support is retained in a slot in ends of the pivotable yoke by a spring and a cylindrical spacer so that the cylindrical support may freely rotate in the slot in the reciprocating yoke.
A saw blade driving mechanism for reciprocatingly drawing a flexible, abrasive coated wire across a workpiece, said mechanism including,
