I have a Bianchi UM 84 holster. I really like the Bianchi "Quicklock" fastener on it and want to try one for a machete sheath I am building. I emailed Bianchi for info on ordering a few of the Quicklock assemblies, but I got no reply. I know I can spend a few bucks ($$!) for another UM-84, then cut the Quicklock fastener off, but I am hoping someone knows of an alternative source for them...
