I have the TruCut sharpener and like it! Sharpened my old rotary blades and was able to use about 80% of them. It won't take out nicks, so those blades got tossed. Don't press down while the blade is in the sharpener - the sharpening is taking place on the sides of the blades, just like a knife sharpener. Bought 25 packs of blades from Harbor Freight and gave 3 packs to each of my small quilt group members at Christmas - they love them and have had no problems.
