I have a couple of spears here at home, on none of them does there seem to be any similarity with this stick. The weight of this piece, aside from the ovoid section. The heaviest of my spears all have a basically round section and far less dense wood as a haft. The narrow points in relation to the main stick would make an extremely uncomfortable spear.
That cold steel stuff is a little strange to me being a touch fanciful. I paid just less than double the dollar price each!! for the real thing recently but that was a little unusual to my mind.
