in general, people who can't sharpen knives seem to like serrations. people who can sharpen knives don;t seem to find a need for them as much.
there's always an exception, and making fuzzies would seem to be it when it comes to serrations.
they do need special tools to sharpen, and will probably get sharpened less ofen, but will cut for longer than a plain edge, altho sometimes not as well.
and finding a SAK with the Philips on the end instead of the middle seems to be a challenge. i had one long ago, but most seem to have them n the middle of the back, and that makes them impossible to use on some things, simply not so handy on others.
