Oh, I don't know. My view is that anyone who wants to "walk into darkness" should have a clear mind, a calm hand, and the foregone conclusion that stepping out into the dark world is probably a 50/50 chance at its best. Yes, I still have my nose, it's just that it has been broken twice. My left ribs don't match my right ribs, but then, I'm not really sure why or when.
Buy a couple of really expensive knives because these items actually work. I have found that "running for my life" is usually the best choice I have ever made. I've seen a metric ton of cheap, worthless knives. My adamant suggestion is to find a well-known, intelligent and calm cutlery specialist, especially if he is Sicilian.
Oh, make sure your bevel is uniform in width from front to back and from right to left. You won't be slicing potato salad, just the angry guy who eats most of it...
