No problem. I've been using it a couple weeks now, and really love it. Passed the paper test out of the box, but I compared it to my Ruike F118, and noticed that it wasn't even close to as sharp. A few minutes on the Sharpmaker, and my P128 is just as sharp. Now when I do the paper test, you can barely hear it slicing, the same sound that comes from my higher end Japanese kitchen knives.
