As others have noted above, the best way is for tool using humans to learn the skill to properly sharpen their knives with a sharpening stone (japanese water stone, oil stone, diamond stone, I don’t care…).
But, I also realize that a lot of people aren’t going to learn that skill, or do it well. And though every fiber of my being would be sad if you dragged a knife that I made through one of these beasts, at least it has people using relatively sharp knives. Dull knives are dangerous knives.
A comparison would be an adult who only reads “romance” novels or similar “not literature”… Yeah, maybe not the greatest wordsmithing out there, but they’re reading eh? Which is a lot better than a lot of people.
So yeah, this is the knife version of a “book” with Fabio on the cover, but at least there’s an effort being made.
(though I’m snobbishly going to say that if you use this sharpener, don’t waste money on good knives. There are cheap and serviceable knives that you can abuse that will do just fine…)
