I have the TruCut I purchased thru Nancy's Notion. At 1st I didn't see much in the way it sharpened but found out I wasn't using it properly. It comes with a tube of oil which you need to add to the stones. Also I found I wasn't sharpening the blade long enough and I think that's where most of my problem layed. I tend to wait till I have a bunch of the blades needed to be sharpened before I bring the sharpener out and this last time I reread the instructions, oiled my stones and sharpened for the amount of time necessary. My blades are now sharper than I think they were when I pulled them out of the package. So for me the TruCut works by just reading the instructions correctly. I tend not to read them most of the time but this time it worked.
