I know about Dr. Seuss. I've been on IMDb long enough to run into him and his like. I know this is going to come off as me being rude, and I'm not trying to be, but I really think you need to take your own advice. I see you responded to him after you told me to ignore him. I think he's funny in a certain context, and as such he doesn't really bother me, but if you (and others) keep responding to him by calling him a troll and this and that, he's just only going to keep it up. I won't say he'll go away if no one responds to him, but at the very least he could be the virtual bully who no one will acknowledge. Think about it.
I've always wondered that as well, why they called it a glaive. I do remember, however, in the Atari video game it was called the Krullux, not the Glaive.
Glaive sounds a lot better than dagger boomerang or death frisbee. Also, it's not a commonly known word, so it sounds more potent than flying sword or throwing star. And foreign names like Chakram or Shurikin don't sound as good as Glaive. Really, what else could you name it and have it still retain it's aura of nobility and power?
