In the upcoming “Game of Thrones” episode – “Eastwatch”, we know from the trailer that the Night King and his White Walker army are nearing the wall. Bran saw this in his vision and sent a raven to Jon. Jon has been in Dragonstone for the past three episodes and has been mining dragonglass to be forged into weapons.
Two known materials can be used as weapons against The White Walkers. In Season 3, Sam discovered that dragonglass can be used to kill White Walkers. In Season 5, Jon discovered that Valyrian Steel can kill White Walkers too.
While it was discovered that there is an abundance of dragonglass in dragonstone, there is not much Valyrian Steel left in the world (of Game of Thrones).
The material is known for remaining sharp forever, strength and light weight. Valyrian Steel is now a treasured rare and finite metal since the Doom of Valyria, but there are still some weapons in Westeros that are made from it. Here are the known Valyrian Steel weapons in the show.
Longclaw
Originally owned by the late Nights Watch Lord Commander Jeor Mormont, he gave to Jon Snow after Jon saved him from a wight, back in Season 1. Mormont had the pommel remade from a bear to a direwolf. In “Hardhome” (S05E08), Jon used the sword against a White Walker and discovered that Valyrian Steel is lethal to them.
Ice
The ancestral sword of House Stark that was forged in Valyria and has been passed down through generations.
Ice was first seen when Ned Stark beheaded a Night’s Watch deserter, and when Ned was accused of treason, Ser Ilyn Payne used the sword to behead Ned. In Season 4, Tywin Lannister had Ice melted to make a new sword for House Lannister.
Oathkeeper
One of the swords that came from Ice. Tywin gave it to Jaime with the intention of making the sword into a family heirloom.
In Season 4, Jaime tasked Brienne of Tarth to find Sansa Stark and to keep her safe. He gave the sword to her, and she named the sword Oathkeeper. In Season 6, when the two met again, Brienne offered Oathkeeper back to Jaime as she has accomplished her task, but Jaime said that the sword will always be Brienne’s.
Widow’s Wail
The second sword that came from Ice, and the sister blade of Oathkeeper. Tywin presented it to Joffrey Baratheon as a wedding gift. After Joffrey had died (at his wedding), the sword was passed down to his brother Tommen, but he was never seen to use the sword. In Season 7, Olenna Tyrell saw Jaime with the sword. The sword was finally used in combat when Jaime used it in the Loot Train Battle.
Heartsbane
The ancestral sword of House Tarly for 500 years. First seen in Season 6 when Sam went home to Horn Hill with Gilly and Little Sam. Randyll Tarly explained the sword’s history and said that the sword would never go to Sam, but to his brother, Dickon. Sam decided to leave Horn Hill with Gilly and the baby.
Before the left, Sam took Heartsbane.
The dagger
The mysterious dagger that used by a catspaw assassin to kill Bran Stark in Season 1. Catelyn takes the dagger to King’s Landing, and Littlefinger claimed he owned the dagger, but he lost it to Tyrion Lannister in a bet. Ned kept the knife with him until Littlefinger betrayed him and took the dagger.
In Season 7 at the Citadel, Sam was studying a book, and a drawing of the dagger was seen on the page. Later in the season, Littlefinger trying to get into Bran’s good graces, gave the blade to him. Bran gave the dagger to Arya and used it when she was training with Brienne.
