After seeing this one, and a few on the forum, and quite a few different strange patents, I find myself pondering a collection. So far tho, I only have this one.
Does 1 count as a collection?
Sadly, someone ground all the chrome off the head of this one, probably to erase user marks, It would have been a definite leave-on-the-table if not for the unusual lock thinggy. (I wanted to play with it and see how well it actually worked)
I think locking adjustables are now on my list tho....
