The RBK Snake Grip™ 5K offers many of the same features found in the ultra-light 7K with the added Snake Grip™ rubberized coating. Snakegrip technology is a skin texture that adds grip to the shaft without adding weight and it won't rub off over time. The 5K also has an extra stiff pre-preg graphite blade that is reinforced with blue Kevlar™ fibers with a lightweight foam core.
