This is the top layer of a hide, which is divided into layers by a splitting machine to different thicknesses. This outside layer will give natural marks and hair-cell patterns if left as uncorrected natural grain. The thickness can vary depending on the standard set at the time of splitting and the purpose. Thereafter the skins can be colored & given many protective finishes. Whether presented for Upholstery, Garment, Shoe, or Saddlery, these are the best kinds of leather as they are the hardest and most strong and valuable layer of the hide.
