I have tried several of the gadjets and never found they were worth the effort. Now I just bite the bullet and order in quantity from eBay. Not sure what the prices are now, but several years ago I could get brand-name blades for about $2. Nowadays you can get no-brand blades for about $1.50 each (brand name are more). My guess is that the no-name blades will still work better than a blade sharpened in a home gadjet. Aside from the money tied up in purchasing the gadjet, the way I look at it the time and effort it takes to try to sharpen a dull blade takes away from the time I can be spending on actually creating a quilt. Plus, none of the sharpeners will correct a nick in a blade; at most all they can do is hone the edge, and that they seem to do somewhat poorly so that the new edge either does not work very well or does not last long (or both).
