The only ones we have seen in the show aredcAg said:
There are roughly 17 items made of Valyrian steel noted through season 6. Seems like a lot to me for something that is so rare.
- Ice (then reforged into widows wail and oathkeeper)
- Longclaw (Jon's sword)
- Heartsbane (The tarly sword)
- The dagger
I believe that is all the ones we know about that people still have.
So you think that 5-6 of these Valyrian weapons in ALL of Westeros is a lot?
