I just got this Smith & Wesson diamond dust sharpener. When sharpening a wavy or a serrated edge then this is a very nice tool to have. I tested it right away on a Victorinox Sentinel to see and I managed
very easy to get a razor sharp edge. It is maybe a little too coarse but usually when a diamond type sharpener is brand new it is extra coarse. I will use this sharpener on my knives.
It is
very easy to use and with such a tool it is much easier to keep the waves intact by just sliding up and down with it and this shape will make sure that the complete wave will be sharpened. I have used diamond type sharpeners from China and they last a long
time.
When you use such a tool on the waves then there will be some burr on the other side. I just usually give one or two gentle sweeps on the complete back side of the blade. Then I finish up with
a less pressure again on the waves. I feel that a wavy edge can be coarser and there is no need for any polished edge here.
I like this Smith & Wesson tool!
