I'm starting to make kydex sheaths for my knives and I'm not sure what kind of fasteners I should use. I've been using interlocking screws but I can't find an smaller the 1/4 long. I'm looking into rivets and am not sure what I should get has any one ever tried rapid rivets on kydex? I know they are intended for leather but I can get a bunch of them cheap and was wondering if they would work. Ifor not what should I use? Thanks
