“I used to feel bad about holding on to things from my past like my Day Runners from the ‘80s, and faxes and stuff.

While some celebrity hoarders hold on to scraps of paper, Angelina Jolie is devoted to her knife and dagger collection. Even though she used some of her collection to inflict self-harm as a teen, Jolie has moved on from the negativity, but still loves her antique knives. “My mom took me to buy my first daggers when I was 11 or 12. And I’ve already bought Maddox some things. We take him to a special shop,” Jolie told W magazine, mentioning that her children are only allowed to play with daggers that have dulled blades.
