Acquired a new sewing machine for the shop. Cowboy Outlaw hand operated stitching machine. Capable of stitching thick leather with heavy thread. I have tested up to 11/16" thick leather. Cast iron and stell construction. Simple to operate. One pull of the handle is one stitch. Knife sheath example. 3 layers of 8/9 oz water buffalo leather sewn with #277 (0.6mm) thread).
