Am I missing something here?  I don't think so, but on eBay:

 Looks like another case of a misplaced decimal point. At least the shipping is free.

Those are not precicely what the seller thinks they are, and they are in rather nice shape, but I still wouldn't give him half that for them...

Aren't they glass pliers?

>Aren't they glass pliers?

Not glass, copper, see how short the handles are? They are for something soft. The reverse clearence holes in the back of the jaw are to clear previous folds in the thing you are bending, like if you were making a box. , but the jaws are short, so not for boxes, I forget what those were specificly for tho, forming the ends of copper downspouts comes to mind.....

The seller is basically correct.   Google "sheet metal pliers" and you'll find all sorts of them, old and brand new.  They were made with a depth adjustment also:

It looks to me like the adjustable depth and the ones without began with the same forging, but the gauge parts were added in what look like clearance holes.  The PS&W pliers came with the depth gauges like the Pexto.   

I have the same pliers.  Got them in a big box lot about ten years ago for a lot less than $100, and they're in better shape.  I also have a pair of the Vise Grip sheet metal pliers.  I can tell you that they will work in some glass cutting applications, since I just used them for cutting 3/8 inch strips of mirror.

Not so much for something soft as for something thin.

Pexto is a P. S. & W. (Peck Stow & Wilcox Co.)  brand name.

They are used to close seams on ductwork in the field by HVAC people.
