This is my first design since the Roots in 2017. The Cambium is a one piece fixed axle yo-yo made from a solid piece of walnut. The shape of this design works well for kick flips, stalls. and pull stars/finger spins.
It has a gap width of 1/16″. Because the wood density can change from yo-yo to yo-yo, this model weighs approximately 36 grams.
