Well, I just got my mt amphibian today and must say it's everything I had expected and more. I've been carring a mini socom for qiute a few months now and could never find fault in it. It seems the most logical kniofe to compare the amphibian to is the commander. Well, for handle commfort, they are near equalBut the mt feels more secure. But that's where the eqality seems to end. The mt has a thicker blade, what I feel is probaly a much stronger lock, and significantly more cuvature to the design. The one thing that gave me a little trouble at first was the opinning device. I found it best to get under it, as opposed off the side. This knife may be my new favorite, and I highly recommend handling one if you have a chance. I'll even go as far to say the microtech exceeds spyderco, emerson, and bm in fit, finish design (most the time). I am not experienced with qc on their end though. -perhaps a weak point. All in all, they're worth the extra few buck in my opinion.
