I realize soft iron forging history, the largest sweet area!
As far as is possible at weight by making face thickness minimum 3mm functionally; in the outskirts
I moved and enabled a further low center of gravity.
Low center of gravity to spurt
Because there is the sweet spot of the head below from the equator of the ball,
An excessive backspin is reduced; from a long iron to a medium iron,
Carrey grows by the strong trajectory which does not lose for wind.
Because the short iron does not lose its appropriate spin and ball muzzle velocity very much,
I cover the some misshots.
