"alternatives" - KEY

Key is Karthik Devaraj's signature yo-yo.

To celebrate Karthik’s debut at the World Yo-Yo Contest 2025, "alternatives" designed the KEY just for him. Built from 6061 aluminum with stainless steel rims and a second layer of stainless steel pressed into the center caps, it delivers a one-of-a-kind feeling, stability and power—tailored perfectly for his latest tricks.

For Inhyeok Edition:
Earlier this year, we wanted to create a special edition of the KEY as a surprise for Karthik - a small token of appreciation for his dedication, travels, and all the work he’s done to grow awareness for the brand.

Given Karthik and In Hyeok’s friendship and history, it felt only natural to reach out to In Hyeok for this collaboration.

As someone who’s admired In Hyeok’s artwork for a long time, teaming up with him felt like the perfect fit.

We’re thrilled with how this turned out, and we’re excited to collaborate with @inhychoi again in the future.

The DAY Edition is the only version of the KEY with a full blast finish on both the rims and body — giving it a slightly heavier feel (0.1g) than other releases.
