Bat'leth

The Bat'leth, or Sword of Honor, is the traditional weapon used by Klingon warriors and is the most used weapon throughout the Klingon Empire. The weapon is a crescent shaped blade with two bladed ends and consists of three handles which can allow the warrior to wield it.

The creation of the bat'leth is almost mythical and was said to have been created by Kahless the Unforgettable. It was said that Kahless created the first blade 1400 years ago by cutting a lock of his hair and dropped it into the Kris'tak volcano, after which he plunged the burning rock into Lake Lusor where he began to forge it into a weapon. This new blade, which later became known as the Sword of Kahless, was used to battle the horde's of the tyrant Molor. (TNG: Rightful Heir)

This story was not widely known as it was a secret only known to a select few and the Clerics of Boreth who used the tale to determine if the true Kahless did return in his Story of the Promise. This prized possession of the Klingon people would be lost for many years during the H'urq invasion of Qo'noS. (DS9: The Sword of Kahless)

This made them prized possessions of the Klingon people who would, usually, fight enemies in hand to hand combat with these blades. In Klingon society, Bat'leth competition's were held which had warriors use their skill in the blade to best each other in combat.
