I keep forgetting that I have these... The teeth on the curved, V and flat jaw Irwins are way too soft, every pair I have is ruined.. then again my main use for locking pliers are to hold down sway bar link/tie rod studs so it will not spin with the nut as I'm gunning it with my 10000rpm 3/8" impact wrench...
The jaws lock on real tight, but working on cars I don't get much lateral space to swing the pliers so my twist sockets are the first thing I bust out. On top of that they're not readily available for warranty, as not many retailers carry them, so I'm a little reluctant to put a pipe to it. I'll post back when I do find a chance, somebody's probably coming in with a stripped drain plug tomorrow.
