Primitive Wooden Handle Spear Hunting Fishing Looming Ice Tool Native?? Any Info Will Help...

Looking for any information on this antique Primitive tool? Recently acquired this from an estate and looking to find out exactly what it is and what it was used for, this is all wood except for the spear one the inside of the top piece, bolts holding the top to the arm, Very old, measures 117" long, the handle starts smaller and then gets increasingly larger when coming to the top piece, I thought maybe it was some kind of primitive hunting or fishing spear, Anyone who has any information would be greatly appreciated. Thanks I apologize this is too large to get the whole tool in one shot...
