Greetings all,

I am searching for the name of this tanto dori disarm technique which appears in both the following videos;

Video 1 (Starts @ 4.09 min) http://www.youtube.com/watch?v=1yacGwi8Kzg

Video 2 (Starts @ 6 secs) http://http://www.youtube.com/watch?v=aicHsMC6rxM (http://www.youtube.com/watch?v=aicHsMC6rxM)

For those who cant view vids - heres my oversimplified breakdown:

1)Uke comes thrusting with tanto (right hand)
2)Defender moves (slides - irimi motion) to ukes right side dodging knife thrust with attackers arm extended infront of them
3)Defender grabs the wrist (with knife) with his/her right hand while his/her left hand reaches over the extended arm and then under entangling it in an elbow lock.
4) Pressure can be applied to the elbow joint (looks like a standing hijishime or ude garami)
5)The defender then lets go with left hand to release elbow lock and then reaches infront (fast) across ukes face - trapping their head in their left armpit. The attacker is now arched back and being held up. The knife hand is still under control with what seems to be an armbar across the defenders stomach.

As you can see uke is finished off in different ways either by a body slam backwards or an arm restraint on the floor holding fingers back (Seagal).

Was just curious, as this has move has been cropping up a few times in odd videos and demonstrations but I have never concluded the name. Looks like an effective technique (I'm always looking to expand my knowledge).
The Aikikai also posted an 'advanced techniques' video featuring it as well, but I cant find the link.

Anybody know the name? Appreciate any answers!

Cheers,

Mankind

sokumen irimi nage / naname kokyu nage in our nomenclature.
... and it's our basic technique / kihon waza for tanto dori, jo dori and, tachi dori sokumen irimi nage.

We refer to it as simply "Tanto dori kokyunage" - along with a number of other techniques. Informally we often describe it as a reverse headlock and it is a staple in our tanto dori techniques. We take it to the mat and kneel with our outside leg down and inside leg up while facing towards Uke's feet. We pin by grasping Uke's knife arm across the raised knee and grasping the back of his neck. By raising on his neck and pushing down on the arm as we lower our knee, Uke flops over on his belly and we pin similarly to ikkyo to take the knife away.

That is what we call kokyu ho, though the variation with a pin as the finish.

"Video 2 (Starts @ 6 secs) http://http://www.youtube.com/watch?v=aicHsMC6rxM"

The technique is called "SHICHIRIBIKI". It is a jujitsu technique. It is an arrest technique basically but it has many other uses like knife taking, elbow break, immobilisation. Normally you start with this technique and then switch to another technique if you want to switch from arresting to a takedown. They said you can walk many kilometers using this arrest move as you dont need much force to apply this to uke.

In the video, nage starts with shichiribiki then sokumen iriminage. You can also use other takedown techniques like kotegaeshi, shihonage, udekimenage and many others. there are 2 different versions I know which are
1) to grab ukes wrist twisting w/ opposite hand so that uke's palm faces upward and outward, the other arm (nage) underneath putting pressure on ukes elbow upward. Nages arm attacking the elbow is perpendicular to uke arm as much as possible. Nages hand attacking the wrist, you can use just one or 2 fingers to control the wrist downward as this doesnt require much force!
2) same, to grab ukes wrist twisting w/ opposite hand so that uke's palm faces upward and outward, the other arm (nage) underneath putting pressure on ukes elbow upward however this time instead of being perpendicular this hand holds your other wrist if you are nage. This hand then makes a "motorcycle revving" motion outward on the wrist to put pressure on ukes elbow. both hands making motorcycle movements to put pressure. difficult to explain but there maybe videos of this somewhere.

I found the technique by chance in a Japanese book called aikibudo sei zui 合気武道精髄 by Toshiaki Hirako 平子俊明. In this style it's called ni no irimi - gyaku kansetsu gan men kime 弐之入身 - 逆関節顔面極め

Funny coincidence, I haven't trained in a dojo where this was used in quite some years and just last week showed it to someone :-)

I call all of these techniques versions of sayu undo. To be more specific though I would say they are based on the principles of the Aiki taiso exercise being put into practice and thus become sayu nage.
