The design of the Sliver, a new yoyo from Mk1 and Spiral, began with a threat.
Jamie (Spiral owner) immediately responded with some slimline/mini thoughts, and a 37mm wide concept that he had been working on intermittently. This was back in 2020, early in the year, before even the Kappa had released.
Talk about a collab subsided for a couple months, interspersed with design questions like, “how wide do you think a bimetal could be before it blasts itself apart?”. I got distracted and worked on the Exia, and some counterweight ideas. Jamie was working on the P40-Warhawk. We traded ideas and tips back and forth. He was preparing for the Kappa release, I had just dropped the Umbra. We talked about yoyos a lot, philosophically.
In May, we got back on track, looking up different slimline widths, and found a range to explore between Heshgod Petri (28mm) and SF 36 (36mm). I made this rough draft:
Jamie sent me his version:
We go back and forth like this for a couple hours until we take a break to think of a name for the collab. Mostly we found cool names that had already been used on other yoyos. Since we’re pals, I bought a Kappa and he bought an Umbra. We like each other’s yoyos, which is a good sign, always. We traded some MTG anecdotes with each other, which I suppose is an omen of things to come! Plus, this important exchange:
I want a good slimline unresponsive that isn’t punishing– me
bro yes let’s make a GOOD slimline– jamie
Several months later (July 2020), Jamie sent me a file called “heck.x_t” which contained a yoyo design.
I sent back a revision where the rims were rounded over.
We didn’t even have a working title for the yoyo, having abandoned plenty of great ideas that were already in use.
Eventually, finally, we thought of something passable: “dither”, referencing a pixel art technique where two colors are blended using a checkerboard or other pattern, which adds texture + the appearance of a third virtual color. It’s a metaphor for how we created the yoyo, of course.
Through this process the design got refined down to something really close to what you see in the production version. 6061, flat cup, same dimensions. We discussed the ‘small’ 8mm axle and decided to simply put it through a stress test once we got the prototypes.
We were happy with it, our teams were happy with it, so it was time to order some. So, I did. And we got the first prototype photos in August, along with the Mk1 Contact, which I was prototyping at the same time.
Later, they came in the mail.
We sent them to the team for feedback, and got a couple notes that resulted in changes for a 2nd prototype. Of note, the weight dropped, the rim cut in the profile got pulled back a bit, and some of the fillets were made more round. The next round of prototypes were blue rim dip, just to try something new. It took a bit to get around to this, due to other yoyo releases, but in February 2021, we placed the order. This is also when Jamie came up with the final name for the yoyo:
The 2nd sliver prototypes arrived at the same time as the 2nd Contact run. They looked cool! I shipped them out for team testing and got to work on the other various MK1 stuff that I had been putting my time into.
The CAD file ended up not changing from this version, but the other really long part of yoyo production was still left – picking colors, designing engravings, coming up with a box & a sticker. This was a collab, and a special one, so I wanted to get really deep into it.
Given the new name & theme, I contacted one of my M:TG friends who had been working on card proxies, and hired her to design box art based roughly on the look of Tempest pre-con decks. This was combined with custom art from a friend-of-a-friend.
The box was designed to fit Magic cards, though it’s thicker than usual to accommodate the yoyo.
For colorways, we settled on making some raws, 2 rim masks, 2 fades, and 2 solid colors. This sort of symmetry makes the reasoning process easier for me, and also provides a handy way to organize the yoyos once they arrive. Of all the colorways, the PK Sliver took the longest to develop, due to the newness and intricacy of the engraving. It’s striking in person, and we all hope you enjoy it (or whichever colorway you get).
The colorway development process usually involves tons and tons of 3d renders, which I’ll spare you. Instead, here’s a photo of the results.
There we go. That’s the tale of the Mk1 x Spiral SLIVER yoyo. I hope you enjoyed it. Maybe you can be part of the story?
This yoyo releases on Friday, January 21st, at 8PM Eastern right here on Mk1yoyos.com and on Throwspiral dot com. (Also yoyoexpert, yoyosam, yoyotricks, and yoyoworld)
