I have the TruCut sharpener and it works as it should. The thing you have to remember is.......the blade will never be like new cause its not but if I can get a little more cutting energy out of it, I'll spend the time to sharpen them. I wait till I have a bunch to do too so I'm not continuing having to go sharpen a blade. I keep the used ones in an empty case they came in labeled needs sharpened. Have another case labeled used/sharpened so I know what they are. Once they've spent their energy for fabric cutting, I put them into a case labeled "for paper only" so I still get a little more use out of them before I toss them. I usually throw the totally spent ones in yet another case labeled throw-aways.
