Which one are you missing? If there's more than 16 it might just be a "weapon crafting" tag that I forgot on some weapon in the database.
I don't have the recipe for the Shade Dagger; that's the last of the 16.
You need Shadow Dagger (Drop from the rat cave boss 20%) and then go to the markethall and the recipe appears.
Thankees! ^.=.^
