I like this work, I'm toting a machine stitched hand made wallet from Saddleback. I wish I could make my own fine leather goods: I've cut the leather out of car seats at the pick-and-pull junkyard, and cut up found leather jackets to get inexpensive leather for projects around the house (upholstery and tool holders). The one leather item I made and sold was a sheath that came with a knife I forged, but that was store bought tooling leather.
The tradeoff with machine precision versus the slightly jagged hand stitching is the strength of the stitch. With hand stitching leather, two threads follow a figure-eight pattern through the material; but machines use a lock stitch where there is a bottom thread and a top thread that lock in the middle. With the hand stitching, if a thread breaks the whole seam doesn't unravel, so while the stitch line varies somewhat, it is stronger. I've used both stitches, it just depends on the application and the taste of the craftsman and customer.
