Aww come on - they only do convex edges, the sheaths are made of paper and the handle scales regularly fall off. Its hard to be nice - and I do speak from personal experience.
did you return it for repair? they have a very good warranty service.
don't like the blade profile? they will profile their knives to anything you want, if you ask them. look at their website. I asked them to remove the 'ramp' on my gunny. they did so for free.

I've owned/used my BRKT gunny for a few years now with no issues.
I skin game, and do other bushcraft tasks with it regularly. the A2 steel is good, blade is great and easy to sharpen, and the scales are perfect. but I really look after my knife; I clean it right after use, and don't abuse it(like all my tools).
after 2+ years, the only complaint I have with my gunny is the lousy sheath. IMO the knife doesn't sit in it right; the handle sticks out too far, IMO. but I bought it for the knife, not the sheath.
I will make my own custom sheath anyways.
if you're having problems with yours, I'd recommend that you send a few pics to BRKT and ask for warranty service.
I bet they repair it for nothing.
