Nerbo, or Nerbo di bue (French: Nerf de boeuf; French Haitian: Rigoise; English: Pizzle; Spanish: Vergajo) - contrary to what one might think, this type of whip is not made with the animal's nerves, it is made of bull penis (or more rarely with that of other large cattle), which is dried, stretched and twisted. The result is an instrument of variable length (generally no less than 70 cm), extremely flexible but also very hard, with a characteristic helical design that runs along its entire length. It is generally slightly thicker at the handle and it gradually shrinks towards the opposite end. Dimensions: 80 cm Tracked shipping
