Thank you so much for taking the time to comment. I couldn't agree more with points 1 and 3. I neglected to mention that all our blades are precision laser cut and come with 9-10 contour out of the box. All blades identically matching. If you have a minute please visit our instagram page. I provide more detailed specifics on the effects of weight savings. We bench marked our design to be better than Step and Tydan,which I feel are excellent products. My goal is to provide the best blade on the market at a fair price. The Colors are simply cosmetic and provide an option for those who may want something different. We will also be working with organizations during fundraising for events such as pink in the rink.
