The 15 was the original Emerson I had wanted but ended up getting a vindicator and commander before I was able to acquire one. All 3 knives arrived with the pivot tight and needed to be tweaked, because of the single detent on the vindicator it opens the smoothest; I may need to oil and maintenance the other 2 to achieve the same action. Both the commander and vindi have lock stick issues but it is getting better with time, on the other hand the cqc-15 has a perfect lock with full engagement of the tang(?). It's tough to pick a faavorite, while like all of my Emersons, despite my original feelings, the vindicator is my current fav. But I really like the size of the 15, blade to handle seems more balanced. And the commander feels the best in my hand. All in all, the cqc-15 is another great addition to my arsenal and I am looking forward to acquiring a desert roadhouse, I think, but recommendations are welcome.
