guided sharpener convexing experiment

[@szilardfineascovasa6144]

Just a long-winded observation 🙂: the bent rod is for convexing; it will work by itself, making the foam-backed sandpaper redundant. If anything, the give in the sharpener will, first, go against your ability to control the degrees of the convexing precisely (if you care about it), as well as force you to go in a single direction when sharpening, instead of back and forth. With a stone, you wouldn't worry about accidentally cutting the sandpaper (and, of course, ruining your edge in the process). Still, some stop-collars may save even your sandpaper and your edge you worked hard for, methinks.

Hi, The angled guide rod make the convex edge by it self, you do not need foam. It works better, and with higher precision with a normal diamond sharpener. If you use a 6 mm thick sharpener the protractir shows the correct degrees when you have 28 cm between the cutting edge and the pivot point. This means that you adjust Chef for different blade width. For eveey thumb you use on the sharpener length you get 1 degree sphere = 3 thumb length give 3 degrees convex sphere. Thomas

Looking at your video there is alot of wobble when u work it. U might be pressing to hard down on it and the knife flexes to. Just a tought
