I find serrations to be useless at best, and counter-productive at worst. That said, for EDC for someone who might have to cut rope or seat belts yet can't sharpen a knife to save their life, serrations might be useful. When new they are substandard vs a plain edge but they will still rip/tear material to some degree even when very dull.
