Rust.
High quality knives are made of a different kind of steel than flatware. In order to hold thinner sharper points, and to be able to handle sharpening, they are made from steel with less chromium and no surface coating — which protects from rusting.
Hot water over time will release free oxygen (unlike O2 which is in the air) which will lead to faster rusting.
