The Shuto Fufuken (Japanese for 'knife-hand whirlwind fist') is a fighting technique used by Trina Baylock. It is unknown who the techinique's originator is.

The Shuto Fufuken is performed by stretching the arms out at the sides and spinning the body rapidly, similar to a spinning lariat move.

This technique was taught by Trina to The S, who later upgraded it to the Shinobi Spin.
