Comment of the professional player joint developer Shingo Katayama
It is a utility wedge in pursuit of ease.
I trim an extra part of the upper face of the normal wedge and realize a super deep low center of gravity by bringing weight to the sole part rear.
Even if duffing is slightly re-, sole slips, and a globe rises easily, and the some mistakes are reduced by a wide round sole design, too.
When a fairway, the back side use it in bunker from the start, I show power more.
