This pliers particular and unique combination of jaw width, jaw length and fulcrum location make it the best we’ve tried for working with Molex connectors. The wire cutters gauge is adjustable with a thumb slide and the return spring locks closed for carrying. Adjustable for 12-24 gauge AWC wire. Nicely cushioned handles. There are dozens of varieties of this type of electrical plier, but short of the specialized and tremendously spendy ($$$$) official Molex crimp tool, this is the handiest. It makes producing clean sturdy crimps fast and easy.
