looking at sharpening systems like the Edge Pro, where it clamps on the knife and uses a little whetstone that you grind it with. I know there are a lot of purists who would say only use stones. But do these systems really work well? I have some new R2 and VG10 japanese knives and i might be a little scared when it comes time to sharpening it XD i just dont want to mess it up. Ive tried using my 1k stone on my german knife many times and it gets a little wavy towards the tip and i know im not doing it perfectly well.
