I'm not an expert by any means, so here is a non-expert view. I have an MOD mark II auto and an emerson mini commander. I usually don't use my knives as tools except on rare occasions. They are pretty much strictly carried for self defense. As far as the MOD goes, it is built like a tank. I really like the way it feels in MY hand and I also like the idea of the glass break on the end of it. As far as the emerson, it grips well, is very sharp (if i need it sharpened, i will send it to emerson), and just the right size for me. But to me, the wave is where it is at. Deploying the MOD, even though it is an auto is nowhere near as easy or fast as the wave feature. If I were in a situation where I had plenty of time to deploy the knife before an attack, I would want the MOD. But, as we all know, you usually don't have alot of heads up of a pending assault. Therefore, I will always carry the emerson before the MOD. Just my nonexpert thoughts.
