The Silver Bullet 3 (SB-3 for short) is a limited production yo-yo manufactured by Tom Kuhn, and the third yo-yo in the legendary SB series. Fifteen units (numbered 0001 through 0015) were first produced in the mid-2000s. In 2012, 100 more yo-yos were produced, fifty as standalone yo-yos, and fifty more for the Silver Bullet Series Set. Each SB-3 also comes with a certificate of authenticity. Considering that it is a limited production yo-yo, that wouldn't be too surprising.
