Best used for all you assassin (not the real ones of course!) wannabes is when you are ready to infiltrate a castle. These kinds of daggers were covered in poison for maximum efficiency and were a favored choice of weapon until the long-range weapons appeared.  When you keep in its sheath it can be lashed to almost anything and it only measures 11 inches. It has double edged stainless steel blade. It really is quality made and has a lot of attention to detail. A must have for all the Assasins Creed fans or weapon collectors. Do NOT use it to do anything illegal of course!
