The BSP is a yo-yo that was released by Anti-Yo in 2008. It featured the silicone IPad response system created by Ryosuke Iwasawa. Both halves of the yo-yo are made from titanium, with one half coated with zirconium nitrate and the other left raw for a two-toned color scheme. These expensive raw materials gave the yo-yo a pretty high retail price of around $350 USD, not too far a cry from the Duncan Freehand Mg's $400 to $450 price tag. Also, the titanium body will produce sparks if the user walks the dog on pavement with it, as with generally any titanium yo-yo.
