Unusual tool

[cgw2also]

 Saw this a few weeks back at my favorite antique store and couldn't get it off my mind so went back this morning and bought it. 9 1/2'' overall, handle? is 6'', with curved blade 3 1/2''. Blade is 1/4'' at top tapering to a sharpened edge and appears to have been pounded on  with a heavy object. Handle? looks like it was made to act as a file also. In its present condition I cannot see any names or numbers on it and would like to get some info on it before I decide whether or not to dip it in my Enviro-Rust. Any ideas on what it was for, who might have made it etc. are welcomed. TIA for any info.

It is a clinch cutter farrier's tool.  I see a lot of those made out of old farrier's rasps.
