large antique tin snips / metal shears blacksmith's anvil hardy tool

Pair of very large antique metal shears or sheet metal snips. These measure about 30" long with 7" blades. They are made to fit in the hardie hole on a blacksmith's anvil (or perhaps drive as a stake into stump ). They would be used to either cut light weight metal cold or heavier stock while hot from the forge.

The tang measures about 5/8" x 1/2" at the tip. These have a patina of age and rust.
