Target: The middle of the shin. “Although in this case you’re not aiming for a specific pressure point, the bone here is vulnerable,” Suh said. “Close to the knee and close to the ankle, the bone is stronger, so go for the middle of the shin.”
Tool: The instep of the foot. The effectiveness of this technique is, of course, greatly enhanced if you’re wearing shoes.
Tutorial: “This kick is particularly good because it’s unexpected,” the kuk sool master explained. “You can use it when the other person is attacking, and he won’t expect it at all. Give his shin a quick kick; there’s no need to scrape down it with your foot. The loss of balance and the pain he experiences will give you an opening to escape or counter. It’s easy to connect with a follow-up.”
Again, remember to use control, he said. “In Korea, I saw someone break another person’s shin with this technique during a sparring match. It does take a certain amount of power and just the right angle, but it is possible. You don’t need to use that much force for self-defense.”
Kuk sool’s inside kick entails driving the instep of the foot into the middle of the opponent’s shinbone. Here, Sung Jin Suh uses the technique to intercept a front kick and cause enough pain to perhaps end the attack.
