Razor Carbons versatility and exceptional performance will have the most demanding freedivers and spearfishers jumping for joy. The manufacturing process involves a continuous vacuum for complete control over production of the blade, eliminating excess epoxy resin and ensuring consistent quality for complete reliability. The precise shape of the carbon skins utilizes different weaves with different basis weights depending on the flex point, transforming the Razor Carbon into a variable thrust machine. When ascending through the water, the entire blade delivers its maximum potential as the angle of the finning action increases. A quick, narrow leg action allows the diver to capitalize fully on the elasticity of the fin tip, especially during extended finning on the surface.
