"Cutlery" I always took to refer to knives.

I'm not sure why I never thought of that before. Everyone here would understand it to mean forks, knives, and spoons, even though it they may prefer to use another word instead (I like "silverware" myself). I'm not sure I could ever say "flatware" without feeling like I was writing in a bridal magazine! (This may be because most of the bridal magazines here come from the US!)
