Once an American original, is now just another Chinese made piece of garbage that looks like an original.  Yes I unfortunately own these, and yes they suck.  The jaws on the new vice grips are so soft the serrations wear down to nothing and then don't hold.  I'm an auto mechanic and use vice grips regularly.  If I wanted junk i'd go to Harbor Freight, get a pair for 1/3 the price, throw them away when I was done and not feel like I got ripped off.  I dumped vice grip and bought a pair of Knipex.  Irwin will never get my business again, ever.

I have tried out gripping pliers from Knipex and Grip-on.  Hands down the grip-ons are the way to go.  Snap-on's pliers are rebranded grip-ons.  Super hard jaws, so far I have not even put a mark on them!  I'm impressed.  I bought the Snap-ons for the warranty if I need it, but if you don't have access to a tool truck the grip-ons are sold on Amazon.  Made in Spain.  Highly recommended.
