Another "Please ID this" thread.
I've just picked up a pair of unusual parallel pliers, with handles in the style of our own Maun Industries ones, but with jaws I've never seen before.
I'm guessing they are to cut and pierce some non-metallic tube or belt.
The hole through the cutter, and punch section is about 1cm, or probably 3/8" clearance since they are American.


They are made by Fassing Products Co. of New York

I'm wondering if they could be for cutting round leather belting, such as that used on old sewing machines, and piercing the ends for the joining clip.
I can't find much reference on the net.
Thanks
Bill
