This is a great knife.  It's both VERY sharp and serrated, so it's good at slicing all sorts of things, not just tomatoes.  For example, it's perfect for cutting piled-high baguette section sandwiches, as the sharp serrations allow you to cut through the crusty bread, lettuce, etc cleanly without having to press down hard on the sandwich and squeeze out half the contents! The forked end is often handy for picking up slices and the knife does well in my dishwasher.
