But why would their family weapons be at Beacon? I mean Weiss' family is all businessmen, so I don't think they would even have weapons. They probably didn't go to Beacon either. I think the same could be said of Blake, who's parents were probably White Fang member as she mentions she was born into it. They would be too busy protesting after the war to try and become Hunters. Yang an Ruby may have Hunter parents, but Ruby mentions that she is trying to be a Hunter because she wants to help people and that is basically a Hunter's career. She never mentions that she wants to become a Hunter like her father/mother; so her parents may not be Hunters either (and because Yang is her sister, they share at least one parent).

I honestly think that the image is the result of Weiss needing to quickly grab a weapon until she can get to her locker. She probably got it from a suit of armor, as even the file is called "Medieval_Sword_1," so there may not be anything special about the sword at all and Weiss just need a weapon.
