I'm interested in belt mount options for sheaths. Anyone know if there's a standard / universal measurement between the screws on kydex /plastic sheaths? like this schf58 or these examples I love this simple mod to add a nylon belt loop! And I'm curious if these holes on a small neck knife like the schf16 be screwed to a belt loop. I've no experience with doing mods like this so hopefully some experts here might know more!
