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.
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.
