User blog comment:Reflected void/Devil Fruit Power Transfer (a theory)/@comment-4374114-20120801151753

Another theory on Teach's power, which many will probably disagree with, is that Teach doesn't have the power but an inanimate object does. We won't know on this until later but if they can give a sword or gun a devil fruit why not put it into a ring. This could possible give that hand control of that devil fruit. Though this would only allow Teach to take advantage of some paramecia DF, since any others would only apply their power to the immediate object, we would need to see what other he may have.
