My tools serve me, not the other way around. It’s not worth the time and effort to wash by hand or sharpen on a whetstone. I don’t need an expensive knife to cook at home. A pull through sharpener and honing steel are adequate. Get the right material and you don’t have to worry about the metal in the dishwasher.
Our household has amazing sets of Henckels knives that are in perfect condition from careful handwashing, professional sharpening…and because they almost never get used. We also have a few relatively inexpensive knives that get use all the time because they go in the dishwasher after use.
