The SpinMaster is a yo-yo released in the early 2000s by YoYoJam. It is a signature series yo-yo of Brent Dellinger. Like certain other yo-yos in the line-up at the time, the SpinMaster is a composite-material yo-yo with a plastic body and metal weight rings. Similar to the B de B Freestyle, the metal rings are inset into the white polycarbonate body. Weighing in at 71 grams, the SpinMaster could spin long enough for the player to complete complex string tricks.
