Driver (1W) TSURUHASHI(pickax) swing

How to hit by TSURUHASHI(pickax) swing of a driver (1W)
I'm hitting SLDR TM1-114S (15.5 deg) with this style.
* The standard loft is 14 deg, but I add 1.5 deg by setting.

Grip:
- Left hand is square or weak
- Right hand is ultra strong ( Almost 90 degrees right rotation from usual square grip )
- Left hand is "Baseball", means don't put the thumb on a shaft.
But the reason of it is, my arthro of left thumb was almost broken. So I can't put the thumb on to a shaft.
- Right little finger is on the forefinger of left hand. It's over wrapping.

Address:
- Stance is quite closed.
Left foot is 20 deg closed, right foot is 45 deg closed. - Waist is also closed.
- Ball position is center and not so far. Tee is very high ( Now I'm using 4 inches tee )
- The rotation axis on the heel of left foot.
- Upper body is quite up-right in left-right, front-back.
- Left arm and shaft is in a straight.
- Face is a little opend.
- Right wrist is a litle floating and grab lightly.
- Left wrist is bended a little to palm side.

Taking back:
- Rotate a body on left heel. - Rotate shoulders then hands are moved low (comparing to Normal).
- No arm rotation.
- No dynamic cocking.
- The barycenter stay in same hight.

Down swing:
- Not concious about a waiting at the top.
- The right palm is always up.
- The lowest point of head is after hitting a ball.
It's descending blow.
- Never face turn, but accept natual face turn comparing to Normal.
Follow:
- No arm turn even in a follow swing.
- At the end of swing, the right palm can be turn a little.
