All our Leather products start from 100% genuine cow hides. Each product is hand cut and sewn to maintain the quality of the leather. At SMI we know that when you use real quality leather your finished product will stand the test of time. For our leather products that endure extra harsh conditions we rivet all stress points to increase life span. When you receive a leather product from SMI you will notice that the leather is stiff and tight just like a high quality pair of shoes. Because our products are genuine leather they will break in overtime and mold themselves to your tools. Leather products sold by SMI are not oiled when you receive them. Apply a Neatsfoot oil, or a comparable synthetic leather oil to your product in order to soften and condition your leather.
