I love to keep some of these knives stashed in the same drawer as my flatware.  I just grab them and go to the cocktail bar to slice lemons, limes, and oranges.  Also, they make a great hostess gift.  The set of 4 has you covered with a serrated edge in the red handle, as well as a birds beak in in the blue handle and regular paring knives for the yellow and green handles.
