Symmetrical kayak paddle blade

Asymmetrical kayak paddle blade

An asymmetrical blade is not symmetric about the shaft—one side of the blade has a different shape than the other side. Because kayak paddles strike the water at a shallow angle, the asymmetric shape lowers the blade deeper into the water and provides additional power and maneuverability. Touring paddlers usually use asymmetrical blades.
