That's not abuse.... that's use.
If your vice looks like new... you aren't using it.
I agree, tools are meant to be used; I don't want new, but a coat of paint and some fresh jaws wouldn't hurt. I do try to care for my tools. Afterall, I've got 3 generations' worth of nicks, dings, gouges and welding slag family members have put into it over ~50 years(?).
I just can't find a set of replacement jaws for it. I'm thinking I'l have to find some generic set of 8" knurled jaws and cut them to fit my 3.5" Craftsman.
