What makes a knife "best" is not the knife, or its features, or whether it is blue class, diamond class, plutonium class, or whatever, but how well designed it is for what the user intends to do with it, and when, where, and how he or she wants to use it. Always begin your search by analyzing how you will use the knife, then look for the one best suited to you. The user, not the tool, is the first consideration.
So, tell us how you plan to use this knife, and maybe we can give you a hand finding the one that is best for you.
