ABSTRACT:
A wrench for tightening or loosening the central mounting screw of a circular saw blade consisting of a pair of lever handles pivotally joined on an axis transverse thereto. The first lever handle carries a wrench socket engageable over the mounting screw, and extends radially from the socket. The second lever is pivoted to the first lever coaxially with the wrench socket and extends radially therefrom, and carries a laterally projecting restraining finger parallel to but spaced apart from the pivotal axis, the finger being engageable between a successive pair of the teeth of the saw. The second lever is longitudinally slidable relative to the pivot axis to adjust the tool to saw blades of different diameters, and the wrench socket is detachably mounted to permit the use of sockets of different sizes.
