Euler is a top-level performance bimetal model from Yoku YoYo Design, designed by KenTech.
In 2015, a mysterious young company released a bimetal throw that had a great impact on the scene, then seemed to go underground for a while. Now, the Euler from KenTech has resurfaced with an improved design, and is being officially distributed by Yoku YoYo Designs.
The design looks deceptively simple. Although a large part of the design is due to the stainless steel rim weight, at first glance this looks like a minor or decorative element, but as you play you begin to understand how all the parts come together to deliver a totally powered-up performance. The light body is balanced out by the heavy rim which delivers superb spin and stable throws. The straight body gives an ease of control, and the rounded edges on the rim have a nice soft catch.
Just like the original, you can’t judge this model by its numbers alone. The legacy lives on!
