Stiletto designed the Fairbairn–Sykes fighting knife, a double-edged dagger with a long narrow point designed to optimize the blade for thrusting, though it was also capable of slashing strokes if the cutting edges were sharpened. Other variations of the F-S knife soon emerged, including the U.S. Marine Raider Stiletto, which was based upon the Fairbairn-Sykes knife, and the U.S. V-42 stiletto, designed from the outset to emphasize thrusting over cutting. During the 1950s, large numbers of folding switchblade or automatic opening knives with locking blades were imported from Italy to the United States. Most of these switchblades were side-opening designs, though
Name-bearing type Name-bearing type Under the "International Code of Zoological Nomenclature" ("Code"), the name-bearing type is the biological type that determines the application of a name. Each animal taxon regulated by the "Code" at least potentially has a name-bearing type. The name-bearing type can be either a type genus (family group), type species (genus group), or one or more type specimens (species group). For example, the name "Mabuya maculata" (Gray, 1839) has often been used for the Noronha skink (currently "Trachylepis atlantica"), but because the name-bearing type of the former, a lizard preserved in the Muséum national d'histoire naturelle in Paris, does
