I wonder whether they are notching pliers, used in sheet metal working to hold thin sheets of e.g. brass together before brazing/soldering? Used in musical instrument manufacture (trumpets etc, saxophones). The aim would be a straight cut in from the edge to a fixed depth.
Never saw one of these.
I wonder if this might be a cutter for thick hard wire? There seems to be a notch (where the cutting edges would be), the curved "lip" on the end working just as a guide to prevent the cutter from "opening-up" from the effort.
Does this make sense?
they look like leather notching pliers (similar to above but for leather so can be a bit less robust), used by watch strap makers and belt makers for putting notches in for buckles. the anvil is rather interesting though. not seen one like that before.
I've just spotted what is probably the maker, in a completed eBay listing.
Peter Shakeshaft of Warrington. The listing shows the name on a drill gauge and on the box.
Shakeshaft was a wire tooling manufacturer.
They could be grip and pulls for yanking wire though a die and cutting it. But i still reckon on them being ear cutters.
Tbink my inperial wire gauge is a shakeshaft, will look next time i open that box.
Ill ask a few folk next time im in the right pub. Not many left who worked that industry any more though.
