The Bushido is a yo-yo produced by Buzz-On in the 2000s. It is a variation of the well-known Element X model, but there are some differences. It has metal weight rings inset into the plastic body, but these are thinner. Along with that, it also has thin plastic caps with notches on them for easy removal. Of course, it also features the SPR system.
