Am putting this down here because some people I know think plain old slip joint pliers are strictly a farm tool. In my recent acquisition, are 4 common slip joint 5 inch pliers, 2 are CEETEES, one is plain, and the fourth is stamped PTI 406, Mfg USA, on the reverse side is nothing. Who made them? for sale to what oraganization? PTI just doesn't ring any bells for me.
