Leather

Leather is an item in Minecraft that was added July 20th, 2010 along with the introduction of cows. Leather Armor is the weakest armor, but easiest to make for a starter set when needed due to leather being easily accessible. It can be acquired by killing cows, which will drop 0-2 pieces of leather upon death.

Leather is used to craft the lowest tier of armor, and has no other use. 24 pieces are required to craft the full set: Although it doesn't make very durable armor, leather is the easiest of armor materials to obtain in the beginning of a new world and can help the player survive the first few nights. Other armor materials include iron, gold, and diamond.
 * 5 pieces for the cap
 * 8 pieces for the tunic
 * 7 pieces for the pants
 * 4 pieces for the boots

Achievements
Leather is featured in the "Cow Tipper" achievement.

Trivia

 * After Seecret Friday 8, chickens would drop leather if killed by fire or fall damage. It has since been fixed.
 * Leather Armour was previously crafted with Wool, and was called "Cloth Armor" in the game code.
