Okay, much of it comes down to personal preference, and what you need the knife for. Are you looking for a smaller knife for more delicate camp chores, a big chopper, or something in between? For a first Becker I suggest the BK-2. Why? Because it's an almost indestructible piece of 1095 steel with a 5 1/4 inch long, .25 inch thick blade that can be used as a chopper when necessary, spits (batons) wood like a champ, yet is still small and handy enough to use for camp chores. For me, if I could have only one knife to depend upon for camping and survival, the BK-2 would be that one knife.
As I said, a lot of it is personal preference. Some may think the BK-7 would be ideal, others the BK-11, but for me, for all around usefulness, I'll take the tougher than nails BK-2.
I don't know whether that makes it any easier for you or not, but that's my recommendation.
