I was going to leave this comment at Tam’s, but lots of people already said it a lot.
1. The first rule of a knife fight is don’t;
2. Your knife must never be seen, only felt;
3. You may carry a scary-ass Bowie strapped to your
thigh provided you have your J-frame near your
hand while the other guy is looking for you to
reach for the knife.
the clips on the MTAC are available in a Velcro style that will stick to an appropriate gun belt. This means that the clips are not visibly hanging on your belt when it is worn under a tucked in shirt.
After I was made by a student in a class that I was teaching, I switched to these, and no one has made me since.
I prefer the wide metal belt clips on the Crossbreed to the skinny plastic ones on the MTAC, but that’s a personal thing (though I do think they’re probably stronger and more durable). Beyond that, I don’t see any differences that are significant to me. YMMV according to your personal needs and tastes, of course.
