Thanks, Fernando, for posting these important pics. Material on boarding pikes, much like other naval weapons, is hard to find. My piece is much more primitive, not like those made for the Sapnish naval vessels, but more like what you might see on a privateer or merchant ship in the New World. It's blade is more leaf-shaped, placing it in the pre-1800 time frame. I will attempt to post a pic soon, as I do wish to get others input on it. Thanks again for posting those pics. I've heard of, but never seen the double-headed pikes (chuzo). You'd have to be pretty daring to have to face one of them while clambering over the rail of a ship!!
