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.
Most people almost never sharpen their knives so from that standpoint using a pull through sharpener is already an improvement. Dishwasher I don’t understand however. If I always put my kitchen knife into the diswasher after use I’d never be able to use it because it would be constantly in there. Instead I just quickly scrub it under hot water from the tap and dry it with a towel. Takes me 15 seconds and it’s ready for next use and stays razor sharp for months.
I have a dishwasher that has silicone inserts for knifes. But i also hand sharpen my knifes a lot, someone i’d rather sharpen a knife for 15 minutes than cleaning it from hand.
