I don't have the 0121 but if I needed another fixed blade, I would certainly give it a shot. I like the steel used, the size of the knife as well as the blade profile. The recurve blade, however, could pose a problem for you in the sandbox because recurves are tricky to sharpen. If that's not an issue for you, I think the 0121 is worthy of consideration. Remember though there are many solid fixed blades of similar size and for similar money that don't feature recurve blades. Good luck to you in Afghanistan and thank you for your service.
