From MK1: The Spyglass is the latest yoyo design from Mk1 Yoyos, our third bimetal, and eighth release overall. It takes design inspiration from previous Mk1 releases, the Diffraction and Contact, combining them into something wholly unique in our lineup.

It has a compact round shape with a deep undercut near the response, carefully tuned to match the material location of the circular steps in the cup. Compared to other Mk1 yoyos, it’s smaller and denser, giving it a unique feel while still having good performance.

I documented the design and production process on YouTube in a video series called Mk1 Mechanics. I encourage you to watch it to explore the entire development process from start to finish. There are quite a few already in the playlist, but expect a few more videos to round out the end of this yoyo’s journey to completion!
