Better is a relative term, and as the others have already stated, it is really a question of what you feel your needs are in the way of knife use. I am certain that there are knives out there more suited to specific tasks than what you have, and likewise yours may be ideal for a given situation as well. We are quickly coming to a forum caveat on knives, which I will try to recite here:

The best knife is the one you happen to have on you at the time, whatever that may be.

I guess you could call that a caveat, or maybe an altruism, or who knows what you'd call it. The point is that you are at least carrying a knife on you that you are confident with using, and that is 99% of the objective to be as prepared as humanly possible. Right now I have two knives on me and one in my shoulder bag within arm's reach. I am confident that I can use any of these knives to survive with, the big Swamp Rat knife if I have to bushwhack, make firewood, or lop heads, the KA-BAR Mule if I need a good all around service folder, and the little itty bitty SAK classic if I need to whittle up a firestick or perform field surgery. Each is more suited to a given range of tasks than the others, but I can get by with any one of them in a pinch, as with any other knife I might carry. It may be a stretch to think that I am going to defend myself with that little itty bitty knife, or to pull a sliver outta my finger with that big brute, but that's where innovation and human ingenuity come in. It is of far greater importance to be able to figure out a solution with what is at hand rather than to fantasize about what may be ideal, or at least better than what we have in our hand at the time. One method will serve you well in survival situations, the other will end up as regrets as you go down for the third time.

We've had an abundance of fairly generic interrogatives about "what is better" for any given category of equipment. Looking to upgrade is always going to be a part of preparedness, but it would help if folks would have in mind some particulars about what exactly it is they seek to improve on from what they have; they're likely to get a more meaningful and less argumentative response. In fact, asking such a question anymore seems like a setup, in which you will see such responses as what Chris and Ironraven put up there; good responses both, but very qualified and just a hint of defensive maybe.

CBTENGR, can you elaborate on what it is you are looking to improve upon, or may think could use some improvement from what you have now? That would help quite a bit.
