16: Sipjin wristlock

Source: TaekwonWoo
Today I'm writing about a set from a Kukkiwon poomsae, Sipjin. This is out of personal interest: it's the only example of a spiral wrist lock (called sankyo in Aikido) I've found in a taekwondo form. The set is:
  • 1: Bull block (double rising block)
  • 2a: Pull fists away from each other
  • 2b: Right back stance left augmented outward block (inner-forearm block), right palm touching left forearm
  • 3a: Slowly open the left fist and turn it inward. Slide left foot to shift into left front stance
  • 3b: Right horizonal fingertip strike
  • 3c: Left hand punch
  • 3d: Right hand punch

The opening of Sipjin may be used as a rear bear hug quick escape. Lift both arms to loosen the opponent's grip, pulling their hands apart (step 2a) if necessary. This escape is commonly taught in self-defense sets, although it's usually accompanied with dropping one's weight into riding stance.

But if the opponent gets a secure grip, this quick escape is unlikely to work, so Sipjin contains other options. The first of these is the sankyo lock. This can be obtained by gripping the knifehand of the opponent (either their right knifehand with your left hand, or their left knifehand with your right hand) and then slipping under one of their arms, granting you the wrist lock.

Step 2b, the "augmented block", encodes the wrist lock. Here the primary "blocking" hand grips the opponent's right knifehand, twisting their wrist, while the supporting palm grabs their fingers.

The next movement in the set is the mysterious hand turn. We use this to transition from sankyo to a thumb lock. Doing this allows us to twist the opponent's arm even more as we pull our left fist to our hip for step 3a, causing them to lower their shoulder as you pull back their thumb. To aid this, you also push down their shoulder with the open-handed strike (step 3b)

Follow with two punches (steps 3b and 3c) to the back of the head.

A variant is to use your left thumb to push in the back of the opponent's wrist instead, rather than hook their thumb, but when practicing with a student we found that the thumb lock allows more control via pain compliance.

Now, wrist locks in a taekwondo form might seem like a stretch to some people. Is there any historical evidence that taekwondoin would put wrist locks into their forms?

Oh, look, a very similar lock from a 1969 taekwondo manual. The difference is that the hands are switched.

Joint locks in early taekwondo are old news. It's hard to realize now, but taekwondo was originally founded as a mixed martial art, incorporated both throwing and locking techniques. Ørjan Nilsen over at Traditional Taekwondo Ramblings has a great post on this called Taekwondo and Joint Locks: A Historical Journey. The core art is still striking. Notice how the point of the lock in Sipjin is to get to the back of the opponent's head, which we then punch.

Although taekwondo's locking and throwing techniques are no longer commonly taught, they were preserved in the forms. Finding the techniques is the way to resurrect these old ideas and increase our understanding of the art.

In other news, The Study of Sam-Il is almost finished. I'm adding a few more drawings.

15: Juche two-direction kick

Juche is a controversial pattern. It is often cited as being too "flashy", full of challenging kicks rather than practical fighting techniques. Juche is the last of the five "new" patterns; the others being Eui-Am, Yong-Gae, So-San, and Moon-Moo. These patterns were added to the original 20 in order to incorporate more physically challenging techniques. Juche shares similarities to these four previous patterns, such as the slow motion turning hook kick from Moon-Moo.

But Juche's challenging design doesn't exclude self-defense applications. Take steps 37-39:
  • 37: Flying two-direction kick (twisting kick with left leg, side kick with right leg), also called a "split kick"
  • 38: Land in left diagonal stance twin palm rising block
  • 39: Step left leg forward and turn clockwise into right cat stance side elbow thrust
From a standing position, it would appear we are kicking two separate opponents at once while defending a downward strike from a third opponent. But remember that in patterns we actually face a single opponent, not multiple opponents from different directions. While the two-direction kick doesn't make much sense from the air, it does make sense from the ground as a knee bar. This technique appears in at least two old karate manuals: The Bubishi and in Kenwa Mabuni's 1938 book Karatedo Nyumon.

Here the top of the foot for the twisting kick is used to hook the opponent's heel, while the side kick pushes the opponent's knee. This straightens their leg and forces them to fall over. You can watch a video of the technique here. Given that Gen. Choi and his commanders read various karate manuals, and that Juche was the last pattern created, I believe there's a good chance they came across this technique and that it is the inspiration for the two-direction kick.

A variation is to switch the feet: use the side kick to hook the angle (pulling with the back of your foot) while you use the twisting kick to push into the opponent's knee. This is shown in the gif below.

The Rising Block

The takedown leaves both you and your opponent on the ground. We want to end up in a more advantageous position, so rather than simply standing up, the form instructs you to lift the opponent's leg as you stand up so that you may pin them. The leg lift interpretation explains the use of the twin palm for the rising block, a detail that to my knowledge is unique to Juche.

Ironically, the application from the Encyclopedia of Taekwon-Do (right) is close to what I envision for the set. But rather than defensively blocking an axe kick, you are actively lifting the opponent's leg as you get up from the ground, and they are ideally still on the ground. Also, the fact that we are in a left diagonal stance suggests to me that we lift the opponent's right leg, rather than their left leg as is shown in the right image.

Finally we use step 39, the clockwise turn into the side elbow thrust, to twist the opponent's ankle, forcing them (if they are on the ground) to spin onto their belly.

After we flip the opponent onto their stomach we can disengage. To reiterate: we lift the opponent's right leg and turn clockwise to flip them. One way you might do this is to grip the opponent's toes with your right hand and their heel with your left hand as you twist their foot with the turn into the side elbow thrust.
