I confess I provided my feedback/suggestion, less towards the community asking for advice — Not that I don’t appreciate you chiming in Tcmeyer/MarcH! — But to whoever is selling this system. From my own experience, I’ve always wanted to know what drove someone to buy a system and what drove people to recommend it to others.
To that end, I’m grateful you brought up this video, MarcH. This video? Is 100% the only reason I bought the sharpening system. My attitude was “if this dude can figure out how to sharpen a shun, I can figure out how to sharpen my yoshihiro” — So that’s why I BOUGHT the system. There are not a ton of great posts that discuss these knives on this forum/reddit in combination with WickedEdge.
But what stops me short from recommending it to other mates who use similar knives (lots of Japanese knives are single bevel/chisel grind) is the deficit of official materials/FAQs to comfort prospective customers that this system can be leveraged effectively in those circumstances.
