I attended a build night with a few friends from our university's realm and someone brought up an interesting weapon idea. A chakram, now we would have classified it as a rock and just make a foam frisbee without a center. But then I asked, "what if it could be used as a slashing weapon?" Then we started debating about crescent moon blades and their legality. The head of our realm said he wasn't sure so I decided to ask on here. The intended shape of the weapons would be similar to this
.
If the weapon is legal I'm hoping to use something like this for a core. And then dap and wrap it twice or thrice. To get a good grip on it I was thinking maybe drilling a hole into the wood ends and slotting through a piece of fiberglass core.
The weapon would be intended for practice only as a means to help train blocking and speed.
