I picked this spear up at a recent auction. It was represented as a Polynesion fishing spear with shaft cut off. Can anyone give me a better idea of what is or is not?

Blade is 6 inches long to shaft and 1 inch wide where the blade meets the blade shaft. Overall length is of blade and ferrule is 13 inches. Blade is mildly magnetic.

Whats left of the wooden staff is 11 1//5 inches to the ferrule. It is covered in a leather like material with three bands of heavier leather with spiral lacings. The lacings are hard but I can't tell what.The width of the lacings and bands are variable...not uniform inwidth,

This may be a tourist piece but not of real recent vintage. At worst it is an neat looking piece of iron.

Any one have any ideas about what this is, or is supposed to represent? Is it realy a Polynesian Fishing spear?
