The Ohyo Spin It was a short-lived boutique aluminum yo-yo with a shape that was somewhat similar in appearance to the Tom Kuhn Silver Bullet and the Tom Kuhn Silver Bullet 2, but instead of rounded rims, they are flat.
While the copyright on the card inside the display box says 1999, the "OHYO SPIN IT" trademark filing date of December 04, 1999 means that this yo-yo likely came out at the end of 1999 or sometime in early 2000. The trademark's "first use anywhere date" and "first use in commerce date" were both November 30, 1999. The trademark was cancelled December 01, 2007.
Used a size C, shielded ball bearing axle. Notice there is no response system of any kind, just like the early Tom Kuhn SB and SB-2.
