I don't cook, but I clean and tidy the kitchen so I see the mess that is left for me to clean.
Being kitchen noob I think all the knives we have are BS and I always grab a serrated steak knife to cut everything cause there are about 20 of them and then can go in the dishwasher. My rule is "if it can't go in the dishwasher it can go in the bin*."
Yes I would put your fancy knives in the dishwasher too if you didn't clean it yourself and put it away.
Steak knives all the way baby. I cut onion, tomato, meat, plastic, wood, bone, vegetables with our steak knives. All the other knives just get in the way of progress.
*unless it can be pressure washed on concrete path when I'm going the car rims
