Use of the Crescent Step

When I began to get serious about my study of kata application potential,
I spent much time looking at many
of the unlikely movements in kata.
One day I thought about the differences of stepping between different Isshinryu groups.
Some just stepped out straight,
Some used a combination of straight stepping and the crescent step.
Some just used the crescent step when moving.
I thought about this long and hard,
And 20 years after I began could only recall being shown to use the crescent step.
The closer I looked, the more I saw.
The use of the crescent step was a force multiplier,
Allowing you to use the compression into your centerline,
Then the explosion of stepping out from the centerline,
Exploding, expanding your energy into your techniques.
It also allowed you to use your kata technique in a new way,
Attacking targets on your opponents lower body.
There is more, but enough for now.
So I made sure the only method of stepping we would use was the Crescent Step.
It became an obsession.
Here are some of the reasons why.

Use of the Crescent step
1. stepping – on top of opponents foot / stomping
2. stepping – hooking behind on the interior line of defense

3. stepping – hooking behind on the exterior line of defense

4. stepping – stepping on the opponents instep

5. stepping – hurried stomping on the opponents instep

6. stepping – sweep

2. stepping – inner knee check/thrust
This might where the use of stepping was also a form of kicking,
Such as used in Chinese Tam Tuie.

There is a lot to consider,
These illustrations are just several of the possibilities.
Targets for stepping
1) Thigh, mid to lower, lateral part (Fukuto) – causes severe pain, muscle cramping in thigh, pain in lower abdomen and loss of leg motor function.

2) Fibula, Middle (Kokutsu) – central lower leg on the front of leg. Causes severe pain (fibular nerve) and loss of posture.

3) Soleus Muscle, lower part (Kusanagi) – lower part of calf muscle. Trauma to the tibial artery and nerve, also producing pain in abdominal and hip regions. Causes loss of motor function.

4) Lower Inside of Fibia – causes severe leg pain.

5) Medial Malleolus (uchikurobushi) – Point just below the ankle bone. Causes trauma to tibial artery, pain in the hip area leading to loss of motor function.

6) Instep (Kori) – Point is on top of foot between temdons of big toe and 2nd toe. Causes pain in leg, hip & abdomen, with loss of motor function.

7) Foot, top of (Soin) – Point on lateral side of foot, about 3 inches behind and central of small and 4th toes. Causes pain and loss of consciousness.
