Double Augmented Forearm Blocks

There's little on the Morote Chudan Uchi Uke or Taekwondo's Double Augmented Forearm Blocks on the internet. Most of what I've seen - even from sources I usually respect, show ludicrous explanations of this technique.

Mostly I think it's related to the key terms 'augmented' and 'block'. Once you think of it this way and try to search for a meaning or application for a very strong blocking technique, which is how this technique was taught to me, you start grasping for straws and are forced down a garden path to some very poor kata or hyung interpretation.

So if we stop looking at those main terms, try not to follow the trend of seeing everything like a handlock, and ask ourselves how to really hurt a person with this technique - this leads you to different options for holding your two hands out like that. Yeah sure I guess you could apply a nikkyo or 'Z' lock and put pressure on the elbow using your forearm (I've seen some high level hard stylists come up with this). But come on ... that's stretching it, don't you think?

What I came to the conclusion of early on is that the back hand plays a big role in this technique. Not really to augment the front hand as a block. Why would I really want to put my arms into an oncoming strike which might require me to crush my lead arm? Forget it.

What I want to do is to have both hands out so that my front hand can grab hair, wrench the opponent's neck sideways, and punch upwards with the back hand. I could cause some lethal and permanent damage if I hit a person in the chin whilst his head was wrenched sideways. Or if I aim lower, then I can strike without the lethality but still apply some sickening force whilst controlling his head.

Keep it safe, folks.

Never ran into that in my flavor of TKD. In kung fu I picked up some Wing Chun light. I was taught a supported tan sau.

Normal TS

The idea that both the tan sau and supporting hand are up and ready for an attack.

It's less about a supported block if you use a supporting hand and more about the attack.

Great application...this is one I have always wondered about!

Why do you think the follow up movements (such as the punch with the back hand in this case) are not included in forms so often? It seems sometimes we are left to invent purposes for techniques in kata when we view the technique in isolation of the form...leaving it open for some crazy interpretations!

Really enjoy your blog! Thanks!

I think that the back hand is "not included in forms so often" because of our training methodology - the whole entire thing about line drills is about practicing a technique up and down the line. The back hand goes to the rib or hip so that it can be fired again. And the focus for hard stylists is about the 'finishing technique.' This is my hypothesis from the introduction of karate into tertiary schools in Japan at the turn of the 20th century.

So real martial arts begins when we look what happens between each technique during the line drill - and in my opnion we need to pay close attention whenever both hands come together in their flight paths or when they travel in the same direction.

Bob - when you talk about the supported tan sau - I totally get you. But the focus of your style helps to work both hands. Hard stylists need to make a big leap before they can work it like that.

But I like it that you said the supporting hand is "more about the attack" - I totally agree!

Motobu Sensei is demonstrating mefutode (aka meotode) in the image above. The okinawans called the concept "husband and wife hands".

As you eluded to, it was rarely for augment blocking :-).

The okinawans have an interesting place in the timeline of hard style martial arts - they formulated the Heians as their training methodology. But before that happened, the okinawans would have been exposed to a heap of chinese martial arts - some which initially flavoured my early training. And in my opinion, the drawback-hand-on-hip didn't stop both hands from working well - because chinese arts encouraged both hands to flow and work together, and often performed techniques that required both blocking and striking at the same time.

Big leap for sure - it just takes time. In classic WC (aka the video) you do not support the tan sau. However, in a kung fu school where students have tried other styles experimentation happens.

I do think there is a hard parallel: In TKD we were taught that a block is an attack (aka limb attack). It seems that some KF styles just combine the two. i.e. the block becomes more of a deflection of the limb and rolls right into a strike.
Colin Wee said…
Yeah, I like the idea that a block is an attack. But I also find that it is surprisingly easy for me to combine the more fluid chinese arm movements within the TKD framework. It surely allows me to utilise my hands better than if I were to just use a hard style approach. As you say, it flows from deflection to attack more smoothly. I have always assumed that it is better to slip in a strike than to just wait until the opportunity of a perfect strike comes along. Colin
