Sang sonkal magki application

Hello, I want to run a possible application past more knowledgeable people here. Since I am currently without a training partner The movement is twin knifehand block (sang sonkal magki)


It first appears in the pattern Yul Gok


The application I am playing with is using the movement to break or open up a clinch. Going from the classical back of the neck - tricep clinch I would say we can use the movement to attack the elbows of each arm. This opens the attacker for the next movement in the pattern. Any comments welcome

Hi, Finlay. Would you please explain what you mean by "attack the elbows"? I'm having trouble visualizing.

Also, a good way to test applications is to put them into context with the moves around them. How do you see the spearhand following on from the double knife-hand block?

I suggest you look up Iain's work on Pinan Yondan as this is the opening two movements.

Jesse Enkamp has an application that is along the lines you are talking about. See around the 8:00 mark.  I would recommend testing this one though.

First thoughts on this were a flinch against a haymaker with simultaneous strike to the neck/face and then I also thought of the Karate Nerd application mentioned above.

I think the Enkamp application has some validity (step off line/redirection in a clinch/grab) and then the follow up spear finger thrusts (as seen in Yul Gok) can be palm strikes into the head/neck.

The same technique is in tang soo do version of pyung ahn sam dan. I had many theories, none of which seemed quite right. I've since moved to other styles, including aikido, where I've seen similar motions but not quite exactly this, but similar.

Check out the guy in the black suit in this video. It helps to reduce the playback speed to as slow as possible. He is applying a technique called sankyo against a high strike. Not his hand positions as he intercepts the strike immediately before trapping the opponent and taking him down.

Hi Finlay For me it is an entry to the head pull, but in our version arms are much closer. Short clip below

Kind regards

 at about 2:10 I use Pinan /Heian yondan/ pyung ahn sa dan, double knife hands ( I'm sure its a much more targeted strike to the neck but we're just doing a drill) These are a few drills I use to work crashing through punches and getting to a control position (not holding) embalance to strike, project or takedown. The 3/4 stack or over hook side clinch takedown I do from Yondan (knife hand to x block section) as well. most of the throws are from Pinan Sandan/ Pyung ahn sam dan (sorry my Korean spelling is likely worse than my english!) 

Les Bubka seems to use it with much the same principles in the great video above!

all the best!

Ken Baker uses the move in a bit more detail in this Iain made/inspired (probably varied some at least) Bunkai flow
