Origin? Inuit? Not exactly a weapon, but....
 

I found this in a drawer at a very fancy estate sale; it had been overlooked by the antique buyers. Bought it for the price of a starbucks coffee, although I don't drink that stuff any more.

Is it an Inuit 'ulu'? Or western? Obviously hand forged, the kind of steel I can't resist.

I think it's for chopping herbs or cutting leather (given the ends come to a point, it's more likely that it is for cutting leather, as herb choppers typically have rounded tips). Looks homemade.

[Edit: giving it a bit more thought those tips don't come to a very good point and it does have a T-section handle, which round knives (what the type of leather cutting knife I am thinking of is called) don't typically have. I mean they can but it's more common on herb choppers. So leaning more towards herb chopper now]

I would have been next in line for it right behind you!

I like these things!

It's an herb chopper used with a wooden bowl.

I have one similar that if I can find in a timely manner Ill put some pictures up for comparison.

Looks like your handle is beech wood.

This looks like a form of Inuit ulu. Used for cutting meat, leather, etc.
