Every side, tool, or other types of bag is made one at a time. There is no set pattern that is used over and over. I build each bag custom to what the customer may need. They are made out of 7-8 oz. US cowhide for the exteriors. All of my bags are fully lined with calfskin on the interior. All the hardware is solid brass or stainless steel and available in a variety of finishes from natural to chrome plated. Every bag is hand-sewn and/or laced. They are not throw-away type bags made out of some mystery leather from Pakistan. They are made to be used for a lifetime. As with everything I make with a little upkeep you will not have to buy another. What is available is up to your imagination. Give me a call or email with your ideas. Bags prices can vary greatly depending on the size and many other factors involved.
