there is a move i have seen and i found it very weird and ineffective. its called in japanese a "shishinken" (pinky strike). you make your hand into a fist with your thumb resting on top of your fingers instead of across (which we do for a thumb jab strike/boshiken or an altered fist/koppoken), then you stick out your pinky finger and you strike. can't find any use for it except for picking out little green enemies. 
would like to know if any of the modern folk use this technique/strike?
peace
