KC Jewel is the handle for master yo-yo craftsman John Rollins. John has customized and modified many models through the years, and is especially known for his skill at jewelling yo-yos.
Pictured here is a totally refurbished Duncan Tournament Reproduction. A New axl was installed, the inside Yo walls were re-surfaced, then the gap was reset for the best possible play. 4 Jewels were also set into the face of each side.
