Bucky Balls is a funny name. I think that when talking about this we have to limit it to physical innanimate objects like a typical sword in appearance. What are the Nano people always talking about? Bucky balls and nanotubes? I would say that they are the way to go right now. After all the reason a diamond is strong is because of the carbon inside isn't it? If we form it how we want in to the tubes or spheres I would assume it would be stronger than a diamond or titanium.
