The Hattori is probably the most extreme design in the Sengoku lineup. The holes cut into the yo-yo are not cosmetic and they are not some gimmick; They are there for weight distribution and paired with the stainless steel rings they offer some of the best rim weight you can achieve in yo-yo design! The perfect blend of aesthetics and performance!
NOTE: B-grade Hattori are b-grade for vibe. They look and perform like A-grades, but have a noticeable vibe on the fingernail test.
