TSPROF Pro Convex Attachment

Convex Attachment review

First, I would like to say, that the K03 is my first experience with a guided sharpener of any kind. I have used the convex attachment twice so far. The only issue that I have encountered is that it has a tendency to turn slightly during use, thus changing the sharpening angle ever so slightly. I now have been watching and adjusting this carefully during use. Perhaps I am not tightening the attachment firmly enough? Aside from that, I find the K03 to be beautifully machined, and precise.
