Naw, I gave up on keeping track of those long ago. I made my last one out of a piece of leafspring, then drilled another hole, ran a string through it, and tied it to my bench. That way I always know it is at the bottom of the pile of scrap wood thrown under the bench.
Who says I can't be organized?
(Actually, I found the frizzen spring vise after I got home from work. It was in the box with my horn-working tools. I put it back so I'll know where it is next time I need it.)
