I've got a few knives, fixed blades, non fixed. For EDC (read Every Day Camping) something from the Mora range does the job well. Stainless steel is harder to get a razor edge but will hold its edge longer than the 'softer' Carbon blades. I was given as a birthday present a Fallkniven F1 by a couple of norwegian friends and its lovely but too nice to use so its in a drawer and I look at it from time to time
I've a couple of locking Buck Knifes which are solid but technically an illegal carry on UK streets, fine at camp. Favourite folder without doubt is one of the several Opinel knives I own. Some have a locking collar so technically an illegal carry but the locking ring is easy to remove (and put back) making it legal. All mine are Carbon blades but sharpen right and you can shave with them.
