Have an older Pittsburgh slip joint pliers that has always been balky. Put enough pressure on it while gripping something hard, and the slip notch jumps out of the groove, which can be painful, depending on the circumstances. I tried adjusting the nut/bolt, but it was just a poorly machined tool. Since I had to go to HF today anyway, I figured I'd try out the lifetime warranty on these tools. They don't sell the same pliers individually anymore, so the store manager opened a multi set pliers blister pack and gave me the equivalent size pliers from that set, in exchange for my old pliers. No questions asked. New tool is MUCH better made. Kudos to HF for honoring the warranty in an easy and upright way. Too little of that these days.
