Chris, I'll try to explain myself a little better. Ok, as you look at the blade of a 42 from the side, look at the edge. Now, as you look at the edge and move your eye towards the spine, you'll notice that the blade reaches its widest point somewhere around the middle. Your utility blade(like most kitchen knives) reaches its widest point at the spine. It is ground all the way to the top; like the spyderco military. That's where the difference is. I belive it's called a V-grind. You take that, give the blade a nice deep belly, put two handles on it and you've got yourself one great backpacking knife. Just my opinion. By the way, you're not being irritating at all. I like discussing this stuff. I'm always trying to learn, just as you are. I might not be correct either! Of course, I can't remember ever being wrong! Let me know what you think.
