My dealer and one of my coaches said that the Eclipse blades were basically the same as the Matrix Legacy blades material and figure wise, just by a different brand. Does anyone have any experience as how often to sharpen them? I heard both Matrixes and Eclipses are 50-60 hours because they are stainless steel, but I also noticed that they don't last quite as long as they claim. I've been sharpening around every 20-30 hours, which is working good, but I don't want to wear them out too fast. If the information is important, I am skating from 11-14 hours a week and I am on double jumps. Thanks!
