well my new knives go through the dishwasher and I dont stress about it. One reason I got the knives I did was because I knew it would happen, so got good(ish) knives (reduced from $60+ to $15 each), but not something that would make me cry if found in the dishwasher one morning. The sabatier has been with us since USA, so that is at least 17 years, probably more.
