Length: Sufficient. A shaft that won't bend even when struck, improving the sweet spot ratio. EDGE WORKS Edge Works EG 520-MK S for drivers. EDGE WORKS Edge Works EG 520-MK S A shaft from Edge Works, rumored among workshops to be a shaft that won't bend even when struck, improving the sweet spot ratio. It follows the body's speed smoothly after the swing, and the tip pushes the ball forward in the impact zone, making it a very energy-efficient shaft. It's a shaft that applies pressure to the ball and reproduces an energy-efficient "thick impact," in other words, a shaft that "improves the sweet spot ratio." It was removed from a direct-fit driver during a re-shaft, so it has sufficient length. Length: 113cm Weight: 106g Tip stripping: 3.7cm It has a matte finish, so scratches are less noticeable, but please purchase only if you understand that it is a used item.
