Knives go in the dishwasher and get sharpened with a pull through sharpener
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.
That's fine. They're your knives and it's your kitchen.
If you handwash them, you won't need to sharpen them as often. And if you get used to having sharp knives, you'll stop using that sharpener pretty quickly.
It's like you're saying "I don't need to change the oil in my car. I just spray some WD40 in there every few days until it stops making noise. My car serves me, not the other way around."
That's how you sound. That's why so mamy people are giving you grief.
Nah, it's more like saying I take it to a shop to get the oil changed or fill it up with the cheap gasoline because the point is to get me from point a to point b and I deal with its upkeep. It's not a hobby, it's a tool. But people hear that and want to seem superior, is how I see it, so they tell me the Right way as if I don't know. I just don't agree.
Except you didn't mention getting your knives professionally sharpened, you just said you put them in the dishwasher and then pull them through a sharpener yourself. If you have them sharpened by a pro, then there's nothing at all wrong with that. Nobody says you have to sharpen knives yourself.
Not seeing how a dishwasher dulls knives, unless you're banging them around.
I've heard this for decades, I wash my steak knives all the time, the dishwasher doesn't affect their sharpness at all (and they're proper sharp knives, not those bullshit serrated things).
When all the utensils are in the rack, and you shove a knife in, it scratches against the other utensils, or even the plastic, and moves around depending on pressure during wash. That's why it "can" dull your knives.
It won't be as much of an issue with a serrated knife
Also depends on the metal alloy. Some that make great knives do not have very high corrosion resistance, and a dishwasher isn't a nice place chemically for a reason.
Even some expensive knives can come out spotted and not great after one trip through.
