Ippon Kien hand shape
Ippon Kien is a hand shape, this is where your hand is in a set form to enhance a strike such as a punch.
Instructions for Technique
Ippon Ken is a very good technique to strike at nerve point's. It is acheived quite simply by protruding your second finger slightly, so the joint pokes out of the fist. So not pointing your finger out but just the joint, and connecting with just the point, it can take conditioning of the hands to do this, and for it to be effective can strike anywhere on your opponent's body, but is more effecting to nerve points where these targets open up to you.
