I am very dissapointed in BKT's sheaths. I got a BK7 when I was in Bagram and when I pulled the knife out of the sheath the plastic insert came out to. I guess the glue didn't hold real well. But besides that it feels and looks very thin and poor quality. BUT the knife is great I also have a BK2 that I like very much one the toughest knives I have. My buddy has a BK9 the tac tool thing once again great knife BUT we were gettin ready to go to another fob and he packed it in his duffel towards the bottom and when we got there his sheath was destroyed like in twenty piecesWTFoh ya the sheath is kydex by the way. He's waitin to hear back from becker about it he's pretty pissed. BKT makes some really good knives I beat the hell out of my bk2 all the time I just wish they would make a sheath worth a damn ya know
