Wrist Locks: Kote Hono Gaeshi
|
Kote hono gaeshi or partial wrist twist is a very strong wrist lock that relies on accurate positioning. This lock relies
on the jitsuka manipulating the opponent's wrist into precisely the correct position. As for the other wrist locks the example
shown below is as a release from a grab, but it can be entered into from a variety of armed and unarmed attacks.
The grab being used is a double lapel grab. The person grabbing would either be attempting to restrain the 'victim' against a wall
or be preparing for a head-butt. The use of this wrist lock if pinned against a wall is however not particularly effective as
the movement of the body precludes an effective use of this particular technique.

As the attacker grabs (looks like they swopped who was aggressive here folks!), the jitsuka steps backwards and covers across
with the opposite arm to the wrist on which the
lock will be applied. In the photograph on the left the lock is to be applied to the attacker's right hand so the jitsuka
steps back with her left leg and covers across with her right hand. The hand is pinned tightly against the lapel.
After all we wouldn't want the attacker to let go now they're right where we want them!
By bringing the arm over the elbow is then positioned between the attacker's head and the jitsuka's head. Most
people will find that their elbow is considerably harder than the attacker's head. Therefore should the attacker
follow through with a head-butt, the jitsuka's arm is braced by their own shoulder and deep stance. With a little
bit of aiming, the attacker will find their nose impacting on the jitsuka's elbow rather than a head on head.

The step and cover are carried-out at the same time. This should draw the attacker forwards and disrupt their balance
if done sharply enough. If an opponent is particularly large and/or aggressive, the action of the hand being brought
over the top of the attacker's arms can be used as an atemi. Consider a slap across the face (suprisingly
effective), a hooked punch (you may not need the wrist lock - or you may need it more than ever), or even a sweep
across the eyes with the tip of the fingers (very effective, but you need control and accuracy for that and it is not
safe to practise in the dojo.
The photograph on the right shows the sort of grip that the jitsuka should be taking when grabbing the attacker's wrist.

From here the jitsuka begins to wind the opponent's arm across his body to a position where the opponent's elbow is pointing
up. At this point the elbow joint should have reached a point of tension as should the opponent's wrist. The wrist has a good
range of flexibility in the direction of moving the hand in a flapping motion, but perpendicular to this the wrist is relatively
inflexible - hence the tension.

With the opponent's wrist pinned tight in to his shoulder or chest (on the sternum) the jitsuka should slowly bend forwards
towards the opponent - taking care to bend at the waist and not by curving the spine.
The grip on the hand is quite a simple one hand over hand with the little fingers resting in the notch between the opponent's hand
and forearm. Note that by not interlocking the fingers it allows the jitsuka to quickly release the grip and interlocking fingers
are more easily broken by an opponent's countering attempts.
The lock is effectively trying to put the opponent's little finger onto his forearm. This lock comes on very quickly and
a jitsuka should never apply this lock in haste.

Kote shibori or wrist constriction is a variation on kote hono gaeshi. The entry and movement are exactly the same as
described above except for the final locking action. Still bowing at the waist the jitsuka this time uses one hand to bend the
opponent's arm at the elbow to form a right angle betwen the forearm and upper arm. This means that there is only one hand to
retain the grip, but the bend in the arm increases the strain across the joints and so whilst the lock is in essence the same, it
will come on even more quickly - or as many people intrepret it, more painfully.

In the photograph above the jitsuka is demonstrating the position for the lock. Sometimes the tension is great enough that
the jitsuka can even apply the lock in this position using a single hand without support from the torso.
