Our products (with the exception of Smiths Leather Balm) are custom made in the east Tennessee Mountains. We use two types of leather (excepting the canvas products): FULL GRAIN OIL TANNED / FULL GRAIN CHROME TANNED AND FULL GRAIN VEGETABLE TANNED LEATHER. All leather will have slight differences in the hides. We embrace these characters in the leather as they age over time and deepen the character of the Leather used. There are subtle variations from product to product as a result.
