I have used my little blue one with the sandpaper since at least 2010. And have not purchased a new blade since then. But, I always turn the blue disks the same direction, never back and forth as the directions say to do it. I used to help my father sharpen knives and sickle blades on an old stone grider and he always told me to turn the handle the same direction, never backwards. His advise has worked for me many, many times.
