I'm a BIG fan of weapons. I don't know why, but they fascinate me in a way nothing else can. I've been considering picking up flying kamas, but I'll probably wait for finals to pass before that.
Anyway, I found the urumi online.
---It's a blade!
It's a whip!---
NO! It's the URUMI!
The urumi's blade is usually made of steel and can have any number of blades- the more blades, the more difficult it is to wield. Blades can be of any length, though they are traditionally of one type of sword's length or another. Oftentimes it is dual wielded, although traditionally it wasn't, as this was extremely dangerous for the user. The whip-like blade was designed to require little effort to yield wounds, and if it was blocked, to reach around the shield/sword/other and wound the person holding it in a damned-if-you-do, damned-if-you-don't situation. It is usually taught last or nearly last in every martial art it's used in, due to the severe risk of injury to the user, and even then is first taught with special ribbon versions to avoid such a result.
I'm just amazed it exists.
