This JM&Sons design is hand made with genuine Water Buffalo leather that will burnish handsomely with age and a heavy no. 2 oz canvas divider to keep essentials well organized and close at hand. The portfolio is made using a unique hand stitch technique, called a saddle stitch, making it stronger than machine sewn: 

"When a machine lock stitch breaks, the thread on both sides on the material is loosened and the product becomes weak or falls apart. If a hand sewn saddle stitch breaks, the thread is only loosened on one side and the stitch running on the other side of the material continues to hold the materials together."

In other words, manufactured to last a lifetime.
