From DocPop:

The Original Bolt was a hell of a throw, and was manufactured for over 5 years, with devout fans all over the world. After 12 years, we've taken the best of the Bolt design and updated it for modern play.

The final design is a collaboration between myself (Doc Pop) and Hadrien Bennaceur (who has designed some of my favorite yo-yos) and was manufactured by the awesome folks at C3 Yo-Yo Design, makers of the Re:Master Galaxy, FingerSpin, and Speedaholic (just to name a few). Big shout out to Hadrien, Walter, and Ron for working on this yo-yo with me.

The Bolt Part 2 is made from machined delrin, with aluminum hubs and side caps for better play and longer spins. The caps feature a new "cubby hole" design for horizontal finger spins and delrin body has "schmoove grooves" to reduce string friction. It fits comfortably in your pocket, but still has a nice catch-zone. Most importantly though, it still feels fun!
