About This Part
Under Flat, shortened to UF, is an Attack Type Bit that Takara Tomy released under the Unique Line system, debuting in Japan on August 9th, 2025 with the UX-15 SharkScale Deck Set and later reaching western stores through Hasbro's Booster Pack, Scale Shark 4-50UF. Its flat tip drives forceful movement that helps a combo catch the Xtreme Line and trigger an Xtreme Dash. It is a shortened version of both the Flat and Low Flat bits, standing two millimetres below a standard bit's height, and like Flat it keeps a shallow dish carved into its centre. Notches around its ring mark it as an Under-type part.
