The popular KP-103 has been brushed up with good release and hitting feel. The latest forged model is made from a round bar, forged three times with 1000t and special heat treatment, and the back face and face are also CNC milled with ultra-precise machining.
TECHNOLOGY
精密揫造+精密CNC加工
The head is made from a round bar, which is forged three times using 1000t steel, and the back face is precisely shaped by CNC.Extremely soft FORGED + special heat treatment
The head is refined through forging and then special heat treatment is applied to make it dense, giving it a solid core that transfers energy to the ball while still providing a gripping feel and a crisp, clear sound when hitting the ball.For each club, the impact point is thickened in multiple layers while taking into account the center of gravity, ensuring the rigidity to crush the ball just the right amount, and in combination with special heat treatment, the hardness and thickness give a satisfying feel when hitting the ball.
BEVELLED SOLE
In consideration of easier hitting and release than the "trapezoid sole" used in the KP-103, we have adopted a "BEVELLED SOLE" that boldly chamfers the sole in four directions: the leading and trailing edges, and the toe and heel.The narrow sole width and optimal bounce are effective for down blows, and provide excellent release for a variety of shots and from any lie.
Pearl Nickel Chrome Plating
The matte finish of pearl nickel chrome plating has a smooth, pearl-like finish and reduces the reflection of sunlight, creating a luxurious look.Hardness comparison Rockwell B (The lower the number, the softer it is. Unit: HRB)
