Sean started with the image of a swimmer's hand: reaching out and cupping the water and then channelling it straight with minimal wander. He shaped the blade with a leading edge lip that is slightly tucked (forming a "cup") and a channel running vertically down the center to aid stability and directionality. The result is a super light, concave blade that "hooks up" earlier in the stroke, spills less water, and tracks straight. The carbon shaft adds the perfect flex and quick response that is the trademark of Powerex carbon technology. Cut the shaft to the length you want and then install the handle cap yourself with the included kit.
