Very little description of this pocket knife (called a penknife by some) is given and it could be either fixed bladed or hinged. However, it is known that Dr. Marty Guitierrez did not keep it in good care as it was noticeably dull. Dr. Richard Levine briefly borrowed this knife in 1995 to cut away an InGen radio tag from the carcass of an unknown dinosaur (possibly Velociraptor “giganticus”, Carnotaurus sastrei “chameleo”, or Ornitholestes hermanni) which had washed ashore from Isla Sorna on a beach in a region of southern Costa Rica known as Rojas, fifty miles north from the Panama border.
