This is the easiest, most consistent way to sharpen knives, meaning your beloved chef will not only have a way to sharpen their knives, but they'll actually use it. Knife enthusiasts tend to turn up their noses at things like this, but most cooks, even professional chefs, don't really care about burrs forming and knives cutting paper to a clean edge. We just want a way to sharpen knives to a good edge with little time and effort. This is what the Horel system provides.
In my testing it produced a more consistent edge than any of the pull-through sharpeners most home cooks rely on, and it's smaller to boot. I should probably point out that there are cheaper, knock-off versions of this available. Don't buy them. Their magnets are inferior, the rollers aren't as smooth, and the results are pretty poor. Just because everyone on TikTok and YouTube is promoting them doesn't mean they're good, it doesn't mean they have big advertising budgets. Get original, get holler. Yes, it costs more, but it's better value because it really works. The bundle version linked here includes extra sharpening grits and a nice strop, and makes a better gift, although you can also Buy these separately for $139,
