Query: Komachi knives are awesome!

These are the nicest knives I have ever used. They are very sharp and the coating allows them to slide easily through whatever you're cutting. You can cut paper thin slices of Apple or many other items. The knives are color coded which is intended to help you keep them segregated when preparing a big meal. Use one for meats, one for vegetables.Some have mentioned that you can't sharpen these, but I see no reason that would be a problem. Sharpening affects only a tiny amount of the blade at the edge which isn't coated anyway. But I haven't experienced any loss of sharpness despite using the knives constantly.I'm planning to buy these for my family for Christmas. At $20 each or so, they perform better than other more expensive knives I have purchased.
