These imported 140mm (5-1/2") long parallel pliers have spring loaded handles so they always start in the open position. The broad flat jaws are smooth. These are "combination" or combo pliers, with one jaw flat, the other jaw half-round so you can use these pliers for bending shanks, rings or whatever else you wish to shape. Maximum jaw opening is 3/8", just a little over 9mm. The jaws are 1/4" (7mm) wide.
