TOOL HAVING TWO WORKING JAWS ABSTRACT OF THE DISCLOSURE A tool particularly suitable for use in crimping includes two arm members and a pair of working jaws each supported on a different one of the arm members. A drive arrangement such as a pair of handles is connected to the arm members for moving the arm members relative to each other between open and closed positions. The drive arrangement, arm members and working jaws provide two force transmitting paths each extending between a different point on the drive arrangement where an external operating force is applied, and a different one of the working jaws whereat the operating force is transferred to an article to be worked on by the tool. At least one pivotal connection is provided, in a force transmitting path,between any two members of the group including the drive arrangement, the arm members and the working jaws. The pivotal connection includes at least one pivot member and a bearing member for engaging the pivot member. The bearing member is arranged to deform resiliently when the operating force is transferred to the bearing member by the pivot member. Preferably, at least one of the arm members is formed by two spaced apart, parallel arm plates, and a working jaw extends into the region between the plates. The plates and working jaw between them have at least two sets of aligned openings, and a retaining member which may be of resilient material is closely fitted in each set of openings to fix the working jaw to the arm member plates.
