The clunker on my one bench uses a wrench, I got it off a junk pile cause somebody busted the bolt so the company scrapped the vise. Wrench sure beats hell out of the wimp rod most vises have because a wrench allows you to lock the vise down, and you don't generally come around the corner and catch the damn rod sticking out with a wrench.
I figure come winter again I may get down to mining the pile of scrapped vises I dragged in over the years.
