Just got my new zt 0300 and decided to try making a sheath from kydex for it today. think it turned out well, fits very flat up against my side. took allot of trial and error to get enough material removed to allow it to be pulled from the sheath easy...but not too easy. designed it to leave the clip attached to the knife so that if need be i can stuff it into a pocket. i might make a lanyard for it to dress it up some.
