Crysknife
From Exalted
Formed from the teeth of giant sandworms, these are not considered commodities. They are given, never sold. If one finds a fallen Crysknife it is best to leave it where it is and let the Kif deal with it. The CrysKnife accompanies its wielder on his final (and only) boat ride up The Shadow to serve the defence of Kodor until their last grandchild has joined them.
