The orbital sharpener sounds good on the video, but if some of you have tried it and been disappointed, I won't be buying one. The old "sharpener" I have is totally useless. I buy blades at 50% off, use the old ones (which I store in a case marked "used", as mentioned) to cut paper, etc. They go in the "used" case only have I have flipped them over, put a drop of oil on them, etc., etc., to squeeze every bit of fabric cutting use out of them.
