Bolt was starting to round off and this tool got it out. Really works!

I bought this tool to lock on a shock absorber shaft so I can remove nut on end of shaft

Used these vise grips on Toro stump grinder teeth removed! Broke all of them loose no sweat! My only recommendation would be to buy both size very useful tool

A solid name brand tool. It made the task of taking a heat seized air line connection off of an air cooled compressor easy. Would recommend this tool

Don't won't to carry around an arsenal of tools for that occasional stubborn Nut or Bolt. Then get the IRWIN Tools VISE-GRIP Original Locking Wrench. I've used it a few times and I'm impressed. I recommend the 4 and 8 for large and small nuts. Now, the disclaimer. This will not cover every nut and bolt situation you come across. Compared to a standard combination wrench these pliers are much larger limiting your access in tight places. So don't purchase this thinking it will take the place of a wrench set, it won't. But had I rather have a pair of these in my automotive tool box verses no wrench at all, yes.
