Hair FORK?

So, I have been looking for a "hair fork" for weeks now. I recently saw the movie Chloe, which I loved, and this further deepened my want for one. These are pretty awful pictures, but... you get the idea.

And obviously... it can be used a defense mechanism if need be.... (I can totally justify buying one of these.)

The only one that I have found, that I even PARTLY like, is this Etsy one. Be on the lookout for a plain silver metal one for me! Thanks! : )
