Jon Snow’s sword, named Longclaw, is made of Valyrian steel and is five centuries old. It’s a wonder it has lasted this long, considering how it wobbles like rubber under just the pressure of Snow mounting a horse. Last week’s Game of Thrones was the most expensive episode to date, yet this made it into the final production. Well, to be fair, it took a really sharp-eyed imgur user to spot it and isolate it. The season finale of Game of Thrones is tonight. -via Uproxx
