I bought the TruCut I think from Nancy's Notions and have no problems getting my blades sharpened. I just just put the blade in as instructed and hit the button or push down the lid, whatever it is I'm to do. Its been awhile since I last used it as I save up my used blades and do them all at one time. True the used sharpened blade does not last as long but it gives me a little more use out of it. I just followed the instructions when I 1st got it. When the blade gets where it doesn't cut like it should then I move it over to the case I keep blades for cutting paper items only. I have my rotary cutters labeled so I don't use them for the wrong items. I keep old cases the blades came in labeled too.
