What kinds of materials should I use for leather and kydex sheaths. There are many different types of each. What is the basic kydex and basic leather I would need? Where are the best places to purchase these? What tools do I need for leather sheaths? I'm not trying to go over the top fancy at this time but I would like to begin making sheaths. What kind of rivets should I use and what tools do I need to install them? Basically I need everything haha. Thank you for the help.
