Unique Tongs part 3

This is a really odd pair of tongs, a pair of adjustable scrolling plyers by Thomas Powers an american smith. I cant even work out how they work or how they are even useful, i understand you have different size stock but at its max size doesnt really seem like a size of stock i would use plyers on, id just switch to a scroll dog. I think of all the tongs i have ever seen i dont really see that are in way useful. Seems like a bloody waste of time to me.

This pair of tongs was posted by Matt K a farrier from the west country, he didnt really explain what these tongs are used for. I really need to ask adrian about these because all i can think it is for is holding the shoes while clamping them to the foot of the horse. Need to do some research on these bad boys.

The posts on Iforge are starting to slow down so i think i will only be able to put another post of some really unique tongs.
