Nah man that ****** part of the Razor Puppy series. Don't you remember that episode when Dragoon got all ****** up and had to get to the mergency room from all the cuts?
I honestly prefer the much stronger Metal Fusion Beyblades. Far more customisability, and, they have Metal Attack Rings for the Weight AND clashing together.
Never actually put blades on mine, though I have modified one to accept 3 weight rings, and a needle for the point. Also modified a dremel for the launcher.... Thing would spin for minutes at a time...
