It’s old. Never seen anything like it but I agree with lukem 1820 zombie dispatching device ambidextrous.
You have me stumped Turbo. That is definitely a one of a kind, homemade, duel purpose, thing-a-ma-jig! All homemade tools have some very specific need or purpose. But I give up on this one.
I actually think that thing was crafted to chop out roots. Digger on one end, chopper on the other. I want it.
Looks like it would be used to cut thin canes or stalks on the broad side and strip leaves with the notched end. Just a guess.
When you have a 2 headed hammer, the whole world is a nail! Dunno on that axe Tim...I was thinking something meant for digging/chopping too...just a guess...
