I absolutely hate all my experiences with Knipex collection except the mini bolt cutters. Ive sold almost all the other ones. I have, I think cobra pliers I kept because I hardly ever use that style plier and its very light. They are just so springy - the steel.
I think all the Chanellock pliers are a GREAT deal and value much like Wright tools. I wouldnt buy their screwdrivers or sockets and wrenches, just their pliers which are relabeled for Cornwell, Mac and Matco made in USA pliers.
I have the most Snap-On pliers which I never have an issue with. I didnt pay for any of them, I was reimbursed for them all over the years.
