In the process of finishing off a kydex sheath. The eyelets I have are meant to be used on leather and are too short. I looked at knifemaker.ca but couldn't see any rivets or eyelets? I know tandy has eyelets but how long do I need them to be (using 0.06" kydex)? I've also looked at the american sites and don't want to pay 25% more (exchange) and $20 for shipping a padded envelope.
