Awesome job, Shook I'd rep you but i cant..
It looks great!
Positioning the sword right at the hand and adjustment of the wrist function is a great idea, it allows for so much.....realism.
You can now spin the sword in your hand without actually "holding" it, just with momentum, its uber epic.

Here are a few very basic but fun (to me, at least) replays i made with it

PS: can you please make Uke a sword too? So it could actually be competitive.
