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.

M80 Stiletto tons of cargo. The ship is in length, with a width of and a height of , yet has a draft of only . The M80 Stiletto is the largest U.S. naval vessel built using carbon-fiber composites, advanced composite materials and epoxy building techniques, which yields a very light yet super strong hull. The prototype M80 Stiletto is expected to be in use in less than one year. Ships are expected to cost between $6 and $10 million. Historically, ships have evolved to become narrower and deeper to achieve speed and stability. The M Hull, however, became wider, allowing its
