Let katanas delimb the person holding them

Thing is I'm pretty sure disarming someone with a katana just hits them in the chest, so this wouldn't actually change anything.

I dunno. Personally I'm not a fan of the whole disarm makes a person hit themselves thing, since you've already traded two hand utility for item retention on slip

On the other hand, being able to delimb yourself means attaching the katana to your arm is a bit easier

disarming an item arm hits them on the limb that you are aiming at.
