The F.A.S.T. 301 by YoYoFactory is a high-end metal version of the best-selling F.A.S.T. 201 yo-yo. It is constructed with an aluminium body, the F.A.S.T. response system, and plastic lens caps with printed, serial-numbered paper inserts. Overall, only 121 of these yo-yos were ever produced, and where anodized in blue, black, and silver.
Some of the yo-yos came included with a stopwatch so that the user could measure how long that they could get their F.A.S.T. 301 to sleep.
- This was YoYoFactory's very first full-metal yo-yo, prior to the advent of the Project Red Alert (Redline) series.
- It is also the first F.A.S.T. series yo-yo to be made of aluminum, prior to the release of the F.A.S.T. 400 Series, which had started with the F.A.S.T. 401k.
