Let me clarify: yes, it can theoretically be used as an effective weapon. The Chinese have a number of "wheel" weapons, of which I'm most familiar with deer horn knives. There's no inherent problem with having points going in five different directions, and the backward pointing ones are good for jabbing back or skewering someone who tries to grab your arm.
The problem is that the blades turn in their sockets. Unless they can be held rigid, this feature makes any slashing manuevers useless, and the weapon can only be used to jab in five different directions.
