Inclusion of reinforced jaws, a plurality of parallel oriented jaw ridges (teeth) and holes for the employment of jack bolts allow this tool the option of providing much of the same utility as the common variety of locking pliers while allowing the above mentioned longitudinal force application. This force application is enhanced by the use of impact tools on the reinforced jaw and/or jack bolts.

Abstract: A fish tape pliers is formed with opposed planar and curvilinear edges that form or channel disposed distally from the pliers' pivot connection axis. In one operable embodiment, the edges frictionally engage the fish tape within the channel. The fish tape in pulling an electrical wire through a conduit, is directed away from the handles and the users' grip hand. The jaws may have differently contoured or cross-ridged surfaces to provide the desired frictional engagement without damaging the fish tape. The fish tape pliers includes diverse complementary features for crimping, stripping, bending and/or cutting an electrical wire.
