I'm contemplating buying a BK9 (already have two BK2's, two BK11s and an unfinished BK6 blank) however i really want a good Kydex sheath. I'd want to get an Esee 5/ Esee Junglas style sheath for the BK9. I have an Esee 5 and love that sheath design. Is the Esee locking style sheath exclusive to Esee or does anybody make a similar aftermarket sheath for the BK9? Any recommendations would be appreciated!
