Ken Tsuki

The word “Ken” refers to fist, so this is a thrusting fist, or, a punch. To form this strike the hand is closed tightly and then the thumb is wrapped over the middle bones (middle phalanges) of the middle and index fingers. DO NOT PLACE THE THUMB ANYWHERE ELSE or significant injury may result. Your fist must be closed very tightly to reduce the chance for injury to the hand. The striking surface for this strike is the large knuckle of the index and middle fingers. You should not be making contact with the knuckles of the ring and little fingers instead. If you are you need to refine your delivery method.
