Abstract

Water-pump pliers which comprise relatively displaceable plier handles carry jaws which continue from the handles, these jaws having recesses forming the plier opening and lying on both sides of a jaw-junction plane. These jaw recesses define two deepest points thereof as seen in a longitudinal direction of the jaws and the two deepest points are staggered with respect to each other.

Cited as "prior art" in U.S. patent no. 5,351,585.
