From www.etsy.com/shop/TheBoiseWoodworks "Made from maple with layers of black spectra-ply wood on each side to create a spider-web appearance. This ball bearing style yo-yo is shaped in the classic standard style. Silky smooth to the touch, the yo-yo has an all natural finish of mineral oil followed up by a buffing with carnuba wax. The yo-yo is approx. 2-1/4” in diameter and weighs 2.6 ounces.
The most popular yo-yo's these days have a ball bearing spindle instead of a fixed wood or metal post. Yo-yo's with a ball bearing spindle spin longer, sleep better and make it easier to perform complicated tricks. The yo-yo will screw apart so that you can replace the bearing if needed. The bearings diameter is 8mm. The shaft has a 4mm diameter and is 33mm long."
While visually appealing, the weight of this yo-yo (about 15-20 grams too heavy) makes most string tricks too difficult to make it a practical, everyday yo-yo to play. The Boise Woodworks Etsy shop has been offline since May 7, 2023.
