I’ve seen a lot of different tools that do a lot of different things, but I can’t say I’ve ever seen a pair of pliers that looks like these. I found ’em on eBay, and judging by the seller’s comments, he doesn’t know what they are either.
It seems to be some sort of retaining ring plier or a tool for getting into an assembly to remove a ring pin or valve cover. The only identifying marks on the tool are “Blue Point” and “Made in USA.” I think Blue Point might’ve been a Snap-on brand at one point, but I’m not sure.
The thing just looks odd — you’ll find more pictures on the eBay listing. Is anyone familiar with this type of plier? If so, what wondrous function was it designed to accomplish? Let us know in comments.
