The Sherpa is a collaboration between Yoyofactory and Canadian company CLYW and is part of their Basecamp series. The idea was to make a responsive metal yoyo, something the yoyo world has not seen before, at least not in production models. The Sherpa has a hollow aluminium body and comes with two interchangeable axles, so that it can be played either responsive or unresponsive. It features a slimline butterfly design, reminiscent of traditional responsive yoyos. This is the ultimate evolution in responsive yoyo play and is intended as a novelty yoyo for collectors, rather than a beginner yoyo.
