Hopefully some of you will add a few entries and pictures to this thread and teach me and a few of the others a bit about the different types and perhaps seldom types of engraving vises. I just ran into this vise and for the life of me, I can't quite see how and for what is might be used. Maybe one of you will enlighten me.
