Medieval pole weapons

First is medieval pole arm called Bardiche and I made it from old half broken "plow disc". (It was very hard steel and I broke at least five drill bits when I made those holes for pole sockets.)

Next objects are viking style spearheads from regular steel and bottom left is pole arm called Voulge. It's blade is forged from spring steel and spikes are from regular steel, just like that single spearhead in the last picture.
