Thanks for posting more pictures. I believe it is neither a point or spear. I believe it to be a light duty chisel tool. The tapered tip that forms the chisel was made for this purpose when originally hammered.
Doe's not have the traditional step up socket, usually found in points of ovate socket style.
Has chisel formed bevel tip & not a projectile point which is usually the norm.
Formed to be this tool from the start, not incorporating a step up suggests light duty.
Does not have the appearance of a re-salvage.
What you have is an unique copper culture tool that is complete.
Going back to step up's. What I mean is there is no step wall from the socket, up to the point or blade. It is on the same plane from bottom socket all the way to the tip. If used with force it would create extreme pressure on side wall sockets & hafting(bounce back). The transfer of energy on this type of plane goes from the tip directly to the hafting.
Where as a step up wall between the socket & point transfers all energy to the tip. Very little pressure on hafting which makes a step up, an implement of forward force that is the most affective against bounceback.
I can see your implement as a finishing wood working/ice, etc. tool using normal hand force.
Congrats, what you have is special & authentic old copper culture.....Patina
