There is a group of posters on these forums that will suggest a fixed blade for all situations, kinda their gimmick. Of course, in this case, it is a pretty legitimate suggestion, where they are using their experience to suggest that there is a whole category of blade better suited to the OP's needs, even if not exactly what the OP wants. I tend to agree that a small fix blade like an Izula/Izula 2 would be great to have. They should also say which of the two knives they would take as well, but thats just my opinion.
And on that note, I say the BM Adamas. I find axis locks much, much faster and easier to use for open/close than framelocks. I also think it has a more useful blade shape. As a caveat, I have owned neither, but I have owned ZT framelocks, and BM axis locks, and I am also active duty military with deployment to the sandbox under my belt.
