Blade Semi-Flat (ブレードセミフラット, Burēdo Semi Furatto) or BSF is a Performance Tip released by Takara Tomy as part of the Synchrome System. It debuted in Japan with the release of the BBG-16 Starter Dark Knight Dragooon LW160BSF on July 21, 2012, and in Western countries with the release of the SS-16 Starter Pack Ronin Dragoon LW160BSF in August 2013.
Blade Semi-Flat (BSF) is a slightly wider variant of the Semi-Flat (SF) Performance Tip, mounted on a base with eight left facing "blades" around its circumference. Like Circle Flat (CF), the blades of Blade Semi-Flat are intended to interact with Zero-G stadiums, to help the Beyblade keep balance. While the blades create a miniscule amount of down force, the effects are negligible. In Zero-G stadiums, combinations using BSF are extremely difficult to knockout and the Peformance Tip has the ability to wobble for extended periods of time and sometimes regain its balance, allowing it to outspin opponents. When used in Left-Spin combinations, it is even harder to sway out of the stadium.
