coloured spearhead

[Robert Vermaat]

I think it would be something of a fool's game to thrust a spear that far into a body. Would you be able to pull it out again and bring it to bear before an opponent skewered you?

Weren't these winged spears used against horses? They would be of little use (the wings) in use against humans, and you don't often see them, not in Roman times anyway. Can this spear have been an anti-cavalry spear or maybe a hunting spear? Hunting wild boar, maybe?
