Pliers comprise two branches having an area forming a handle rigid with the branch and having, at least in a proximal part, a cross section whose profile is convex or essentially convex. The branches are pivoted to each other in a region including a coupler and extend beyond the coupler to define jaws. Each handle has, at least in its proximal part, a cross section which has, relative to its mid-line which is parallel to a median plane of the coupler, an asymmetric external profile with a shape which dips more sharply toward one side of the handle. In plan view, in the proximal part of each handle, the geometrical locus of the mid-points of segments perpendicular to the median plane forms a curve whose convex side is directed toward the aforementioned one side of the handle. Applications include gripping pliers such as flat-nose or round-nose pliers, universal pliers and adjustable pliers.
