A small peculiar axe

[fernando]

I take it that this is European ... certainly Portuguese, reason why i don't post it in the main ethnographic Forum ... so far.
Total length 25 cms (10"), quite a small thing; a rather strong blade, though.
The one piece robust handle is in boxwood. The tang is as wide as the handle and secured by copper rivets with washers.
This thing is visibly old, maybe a hundred years, should i say?!
As anyone ever seen one like this?
Coments will be apreciated.
Fernando
