| Description: |  | These parallel jaw pliers feature interchangeble jaws and replaceable jaw tips.  There is  provision for a wire cutter.  The pivot pins can be removed to allow the jaws free movement.  A bar with teeth extends from one handle through a slot in the other handle.  This bar can engage a pin in the slot to form an adjustment lock.  A small cam can be turned to hold the adjustment lock in place. |  |
