ABSTRACT:
A finger wrench or the like for threading and unthreading articles such as nuts or bolts has a pair of slidingly interfitted jaw members with respective finger openings and article gripping edges between the finger openings. In use, the gripping edges are opened out and fitted over an article to be manipulated so as to engage opposite surfaces of the article. Torque is applied through the finger openings. Increased leverage may thus be applied to the article compared with gripping it directly in the fingers, the increase in lever arm being represented by the distance from the respective gripping edges to the finger openings.
