I am in need of a resource where I can obtain sheath making materials. Materials such as stainless steel or anodized aluminum push pins or rivets. I find that the rivets for attaching knife handles to be too thick and don't wanna have to alter each by hand. I also would like to be able to find industrial snap buttons and large ammounts of un-cut thick fabrics such as cordura, leather, and maybe even kydex. I appreciate any and all help here. Thanks.
