The Whistle of the Dead ... now available in silver.
Well, some movies and series say silver would be good against vampires. I mean, don't be ridiculous. Vampires? Whats next, trolls are allergic to garlic? As the deamon hunter you are, you certainly aware of the fact that silver is a good weapon against werewolfs.
Be informed: the particularly sound which comes from this silver whistle is not yet tested against the evil forces so be careful, full moon is rising soon.
Note:
The silver material is very bright and shiny. Some designs look much better when deeper parts are blackened. You can do this easily by yourself by putting the silver jewelry in a small glass with bleach for a few minutes. After it turns dark, you can polish it partial with a sponge or a towel.
