The knife is supposedly a french apache knife from around 1900 (the apaches were parisian gangsters, named apaches bacause of their savage behavior - and known for their fondness for wicked, yet finely crafted, knives and the famours knuckle duster revolver) with a silver and ebony handle. The rust stains on the handle should be from blood - though it could be from many things really. http://en.wikipedia.org/wiki/Apache_%28gang)
