Abstract
A receptacle (74) in the shoe (12) of a circular saw (14) holds an accessory tool (10) which combines the functions of blade wrench and square. The base (18) of the L-shaped tool (10) is bent to provide an offset bearing surface (52) to facilitate its use as a square. The base (18) also includes a hexagonal wrench opening (46) sized to fit the saw blade retaining nut (48). An interrupted longitudinal groove (26) in the 'upright' portion (16) of the L helps guide the tool (10) into the receptacle (74) and hold it there.
