Mk1 Spyglass Design Notes

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. We’re excited for it. Are you?

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.

You can also follow along in the YoyoExpert discussion thread for this yoyo.

The Spyglass 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.

There were two primary design goals with this yoyo. First, I wanted to put some broad steel rims on a yoyo to showcase the bimetal look. I’ve always enjoyed the shiny style of big bimetals, both during casual play and under stage lights. Second, I wanted to bring the stepped cup of the Diffraction back into the Mk1 lineup. I have enjoyed that cup design since the very first moment with it, but it isn’t usually the right one for a yoyo to use. Here it is again, in a yoyo specifically designed for it!

A third less important force was to keep the yoyo design very rounded. This helped keep the yoyo comfortable, and powerful, and it also handed me an opportunity to utilize a schmoove groove once again. This cool feature optimizes midweight without affecting the cup’s design, and here it felt natural to include.

It was tremendously fun to design this yoyo out in the open, showcasing the various design techniques and thought processes that I use to create yoyos. My sincere hope is that it will inspire more people to take an interest in this art.
