I can see where that would be useful, but it would be a limited usefulness. Silver isn't a great metal for making weapons or armor out of. Too soft and doesn't actually keep an edge very well. Though I am glad to see that a few things go across worlds.

I have a knife that's good for killing most things, too. Pretty much anything below a major demon, at least. It's in the Rig's armory, so I can't get hold of it at the moment. Though, if nothing else works, I might risk a break in.
