Why do eggs produce such a foul smell on the kitchen utensils?

Whenever I cook some eggs - the utensils that the eggs got in contact with leave some foul smell which makes me shiver in disgust. I've just boiled some eggs, and I had to slice them: the plate, that I sliced them on, produced that unique, revolting smell. And when I put it into a sink and it got into contact with water, it got even worse. I have to actually apply some bleach on the utensils (or squeeze some lemon) in order to get rid of that smell. Why is it that eggs leave that horrible smell on the utensils they came into contact with (especially in a raw, or boiled state)?
