Masahiko Kimura
The name "kimura" started circulating in Brazil after a judoka and a professional wrestler Masahiko Kimura used it to defeat one of the founders of Brazilian Jiu-Jitsu, Hélio Gracie. This variation of the name gained more prominence in MMA after the introduction of UFC, and the role Gracie had in its early history. Although a top wristlock is technically a reverse double wristlock, UFC announcer Bruce Buffer still announces fights won by top wristlock as "by tap-out due to a kimura".
