Got you all beat  

Used to laugh when Mechs in G-town would come ask to borrow my 60 year old pair of original Vise-grips.  See, Dad lost them and I found them circa 1990.  I still have them.  Put them in my shadowed tool box when I hired on in 2000.  Nothing grabs like these things.  Old rusty skid shoes hardware won't come off?  They will when you clamp Dad's visegrip pliers on them.  I don't care what you got, them things bite and won't let go till you strip the head right off of every screw and bolt.
