What are some cool types of spears/polearms?

I'm just trying to compile a list of cool spears (or weapons similar to spears). So far I have the naginata, yari, hasta, javelin, lance, halberd, and the glaive. The names of any spears you think are cool would be very much appreciated, and a short bit of information about the spear if you have anything you want to say about it would be really cool too.
