I have a couple of the Kershaw brag bags, and though I have not seen the ZT bags in person, they seem to be the same. I know that these bags are available unbranded (except by the original manufacturer), but I can't remember which website; please refer to Nutnfancy's knife storage video, he tells where to get them. Btw, I got two of the Kershaw bags off of the 'bay years ago, and I had put both inserts into one bag and used the other bag to carry my GPS, cord, and dash-mat-mount (I used to travel a LOT for work!), but just last week I had to start using the second bag for knives (both full of Kershaws now, finally!), and I really like how these bags work out. Anyway,good luck!
