John Snow Long Claw Sword from George Martin’s Book of Ice and Fire Series and Game of Thrones Series
For five centuries, Long Claw has been the family weapon of the Mormont home. When the Lord of the Bear Island, Jior Mormont, renounced this title to join the Night Watch, he handed over the sword to his son and heir Jorach. When Jorah fled from Westeros to Essos in order not to be convicted of the slave trade, he sent his sword to his father on the Wall.
Night Watch Lord Jior Mormont gives Long Claw to John Snow in gratitude for saving his life after being attacked by a Whirlwind. Previously, he replaces the top in the form of the head of a bear (a symbol of the house of the Mormons) with a wolf head (a symbol of the Starks). During the transfer of the blade, Jior draws attention to the fact that the name Long Claw is suitable for both animals.
Valirian steel is an alloy of a special kind, which only the masters of ancient Valiriya were able to create. Weapons of unsurpassed sharpness and strength are made of Valyrian steel, primarily swords. According to legends, the Valyrian blacksmiths melted the metal in dragonfire and tempered it with spells. Swords made of Valyrian steel are unusually strong, light and perfectly sharp.
Valirian steel was expensive at the time of Valiriya, and now that the secret of its manufacture has been lost, it is truly priceless. Many blacksmiths subsequently tried to create such steel with their own hands, but they all failed. Some craftsmen, however, know how to work with old Valyrian steel, reforging it; for example, Tobo Mott boasted the ability to forge the Valyrian steel that he had learned at Quohor.
