Shiv

A shiv is a weapon available in The Elder Scrolls V: Skyrim. It is a make-shift blade with cloth wrapped around it, acting as a handle. It can be acquired in the mission No One Escapes Cidhna Mine. Borkul the Beast asks the player to get one for him before he will allow them entry to see Madanach, however it isn't necessary, and there are other ways to get in to see the Forsworn leader.
