Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators.
Tanning is the process of treating skins and hides of animals to produce leather. A tannery is the place where the skins are processed.
A hide or skin is an animal skin treated for human use. The word "hide" is related to the German word Haut, which means skin. The industry defines hides as "skins" of large animals e.g. cow, buffalo; while skins refer to "skins" of smaller animals: goat, sheep, deer, pig, fish, alligator, snake, etc. Common commercial hides include leather from cattle and other livestock animals, buckskin, alligator skin and snake skin. All are used for shoes, clothes, leather bags, belts, or other fashion accessories. Leather is also used in cars, upholstery, interior decorating, horse tack and harnesses. Skins are sometimes still gathered from hunting and processed at a domestic or artisanal level but most leather making is now industrialized and large-scale. Various tannins are used for this purpose. Hides are also used as processed chews for dogs or other pets.
Shell cordovan,cordovan, or cordwain is a type of tanned fibrous connective tissue commonly used in high-end shoemaking. Cordovan is an equine leather made from the fibrous flat connective tissue beneath the hide on the rump of the horse. The leather derives its name from the city of Cordoba, Spain, where it was first produced by the Visigoths in the seventh century, and later also by the Moors. It is a difficult and expensive leather to make, and in the late 19th and early 20th century was mostly used for razor strops to hone razors in barber shops. More recently it has been increasingly used for shoes, wallets, and watch straps due to its aesthetic qualities and exceptional durability. It is also used in archery to protect the fingers. It is smooth and durable, ideal for a finger tab. Shell cordovan has a unique non-creasing characteristic. Because it is made of connective tissue, it is smooth and lacks the pebbled effect of leather derived from animal skin.
