Abstract
A composite pliers has crossed levers, each including a non-metallic body with an exposed metal cutter blade. The pliers includes strengthening and/or retaining structure around a pivot joint which does not extend into handle portions of the levers. This structure strengthens the pivot joint and can help confine the pliers parts in the event of failure. In one embodiment, each lever has a pivot joint strengthening structure insert molded therein, the structure extending into a jaw portion of each lever and protruding from the non-metallic body to form a workpiece engagement surface, such as a cutting blade. In one form, the jaws have more than one row of teeth with adjacent rows offset from each other. When the pliers is assembled from two identical lever members, each row of teeth on one lever will face the offset row of teeth on the other lever so that the peaks of the teeth on one lever fall within the grooves between the teeth on the opposing row. A non-metallic biasing structure is used to bias the jaws of the pliers open.
