What is Arya's new weapon for the Battle of Winterfell in Game of Thrones?

Although most characters on Game of thrones I do not know, Arya Stark is one of the most skilled soldiers in Westeros. It represents a huge threat to the Army of the Dead and perhaps the Night King himself. Before the Battle of Winterfell, she is equipped with a Valyrian steel dagger; his sword, the needle; and a new, somewhat mysterious weapon, that Gendry had made for him Tommy Dunne, the Game of thrones "Master of arms" told Vanity Fair that the weapon is a "stunt".

In the first of season 8, Arya shows Gendry a drawing of the weapon that she wants him to make. Then, in episode 2, Arya convinces Gendry reluctantly to do it once she demonstrates that she is very good at launching dragonglass.

But what does the new weapon do? And why is he so present in the first two episodes of the season?

Arya is comfortable with many weapons, but she has always attached great importance to stealth and strategy. As @thronesfacts points out on Twitter, Arya is particularly good at fighting in the dark thanks to her training at Braavos at Black and White House, where she learned to fight blind with a long spear. It makes sense that she wants a similar weapon to lead a battle that should take place in the night.

The talents of Arya with a spear also come from his training with Syrio Forel, his tutor Braavosi of season 1. The drawing of his new weapon shows that the two ends of the spear, in dragonglass, are detachable and can potentially become two dragonglass. daggers. With the weapon as a whole and as two separate daggers (next to his Valyrian steel dagger), Arya has an advantage over all the other soldiers in the coming battle: she can kill several monsters at once, and can she kill the White Walkers (maybe even the king of the night?) with the dagger.

Arya has also already acquired superior skills using more than one weapon at a time. In season 7, she trains with Brienne of Tarth and defeats her by incorporating two weapons into battle. Brienne is so impressed that she later recounts that Hound Arya no longer needs protection; those who oppose Arya, on the other hand, do it.

Arya is a skilled warrior and clearly has a strategy for the Battle of Winterfell. After all, she knows death. On top of that, her new weapon and Valyrian steel dagger, she is sure to be a most valuable player in the Battle of Winterfell. Hope this ensures him out of the battle alive.
