I do carry a variety of different knives. (No not all at the same time, so don't ask that question
) Some are plain edged, some are partially serrated. I do agree with others that say it depends on how you might use it, but wanted to add that it also depends on how you sharpen it. I hand sharpen on stones, and while you can sharpen serrated (I use a hand held "V" shaped stone) it aint easy.
