Shotokan Karate Pinky Trick?

Question

How do you get person to their knees by using their pinky? I learned it in shotokan karate today but forgot (strange).

Answer 1

you manipulate it. of course if the person attacking you chooses to sacrifice their digit then the fight will continue, also very intoxicated/drugged/enraged people can withstand or ignore the pain.

With all due respect, this is not a traditional Shotokan technique.

Answer 2

I do not think that the trick is something exclusive to Shotokan or any other art.
