All the Kahuna range have the same basic design.
They have a big sweet spot in the mid area of the blade with big, square edges and a high spine to put a lot of wood in the hitting area. To keep the weight down the Kahuna has a concaves scallop of between 3 to 5 mms. The face is flat and there is a bow of 11 to 13 mms. It is suggested that a bow promotes the hands to be in front of the blade giving more control over shots. The toe is also slightly angled so that the bat sits well in the stance position and the hands remain slightly ahead of the blade. The handle on the Kahuna is round a Power Drive design made from specially selected slices of cane bonded together
