After a few back and forths, a Zoom conversation followed and he agreed to collaborate with RSO after I pitched to him my vision for the collaboration. Russell is a machinist himself and one hell of a genius yo-yo designer. Back in the day, he machined his yo-yos using leftover metal bars using a CNC mill.
