Help with identification please

[Inusuit]

I appreciate your input.

Yes, the rounded end of the blade is sharp.

I've tentatively identified the top blade as a bolo, which I realize is a very broad term. As noted, the grip is indeed a socket that would allow attachment of a staff to create a spear or polearm.

What expertise I have is firearms related, which is how I came to my volunteer work at the museum. I am learning a great deal about Asian weapons but remain woefully ignorant and have only scratched the surface.

Again, thank you for your assistance.
