No danger she's a big hard Goth chick who wouldn't be seen with a handbag.Maybe she's keeping it for those pesky animal sacrifices
Not to get off topic too much but my friend is a knifemaker. One day at a knife show a man showed up at his booth and asked if he could make a dagger for his niece. He described her as being a Goth and she liked evil looking things. My friend went to work and manufactured a dagger with a crystal ball as a pommel. The interesting thing was that under its own weight it would pierce both sides of a pop can. So there is some goth chick out there with a perfect animal sacrifice tool.
As for the Mauser knife, I think it is a cool knife and I hope you find it. I need to find one for myself.
