Here we go we are off to the races. That pesky physics thing keeps getting in the way of all the "Better Mouse Traps"! We need one more gimmick in the dive world that will promise to do away with all that hard work in the pool! Maybe some batteries that will make them flop up and down like the SCUBA Steve doll! Look it is simple the strongest lightest blade fine you can find. The only difference might be the shape of the blade. Not split, hinged, or Light up on the dive deck! Ya thats what I want little red lights that blink when you walk so people can see you!
