I've got an older one that says "CUDA CQB1 - ATS34". The IWB Loop is from Blade-Tech, and it needs some brute strenght to close it. If you want to carry it conceiled, the better solution would be a Kydex loop screwed to the bottom of the sheath, so you also can tuck your shirt in between sheath and the loop inside your pants (over the Knive handle). When i made myself an IWB loop for my Fällkniven G1 Garm i simply took an 1" to 1,25" wide kydex stripe, heated it up with a heat gun and swaddled the upper end over a 1,25" file (i carry a 1,25" belt). I drilled 2 holes in the bottom of the stripe and screwed it to the bottom of the Sheath. Works great. If you don't know what i mean, Blade Tech has the same thing on one of theyr IWB Holsters and there is a picture on the homepage.
I really love that Terzuola design, but after a few years of carrying it i found the nice micarta grip is a bit slippery, and for a fighter design, in my opinion, it lacks a propper finger guard.
I got myself the Terzuola Fighter from Gryphon Knives (M30A1) and i'm impressed! The grip is rough and has a propper finger guard. Of course it has no Micarta and the blade surface isn't as shiny as the Camillus one, but it is what it is, a "no shit" Fighter. I love it.
So, if you want to get another one i'd recommend the Gryphon Knives M30A1.
