Hello all,
It's a bit of a long shot as the use for this is probably going to be something regional, obscure & long lost in history!
I found it in the south of Spain (Andalusia) & haven't been able to find anyone who knows it's use.
As can be seen it has a "hatchet", sharpened on one edge as a hatchet would be but it also has the long part on top which appears to only have been sharp at the tip, like a chisel or scraper except shaped, not sure if that's intentional or poor sharpening. It tapers nicely.
18" long (the image isn't at an angle, it's straight on the taper making it look as though it's not).
Marked (just!) as CARRASCO HERMANOS (Carrasco brothers).
This is certainly a strange one! 😉
