I've been reading about various types of hand strikes and the strike with the top of the wrist aka koken uchi came up. We've even practiced this kind of strike in class before. I don't know that I would ever apply this strike in a real, or even sparring type situation, but maybe that is because I don't fully understand or appreciate it. It seems that it would put your wrist at too much rist. So I am curious: Do you practice this type of strike? Do you see it as having any advantages in particular situations? Perhaps specifically as a groin strike? Also, what is the Korean term for this strike? I would appreciate your comments on the application of koken uchi. Thank you.
