I asked this question on here not to long ago myself. The answers I got led me to a becker BK7 from www.camillusknives.com - I also have a Buck Special 119 or just a 119 for everyday use and small camping trips. Both are 7" long in blade length. For a general purpose knife, its best, in my opinion, to get a straight edge all the way with no serrations. There hard to sharpen the serrations when dull and don't do that great of a job sawing if thats what you plan to used them for. It's all about your tastes and your style. Survival knives come in all flavors.
