Everyone else has already talked about the pros and cons of serrated and plain edge blades. 4plait hit on a very good point when my knife gets dull I can pull out my pocket stone and get it back up to speed in seconds, a serrated edge on the other hand takes much longer to sharpen if you can sharpen it at all. Try to whittle a peg, skin a coyote, or peel an apple with a serrated edge.
