A page out from my personal journal showing Toi-gye applicationToi-gye Step 12 - 18 is typically represented as 'W' blocks (in Karate that would be yama uke or 'mountain block'), requiring you to perform them with a hard snap of the arm and a big 'stomp' with the foot. There are a few applications that I actually like which bring more combat value to this technique beyond the swinging of the arms and the stomping down hard.Taekwondo 'W' block - as it is performed in the form Toi-gye step 13The sketch above from my personal Taekwondo journal shows off the W block as a leg capture and take down.
