The American flag spring assisted knuckle knife was designed in the USA. When extended it resembles the trench knife that was named for its use in trench warfare during WWI however our version is foldable to make it more compact and easier to carry. There is a small spike on the tip of each knuckle and a window breaker on the bottom of the handle. It features a 3.5″ 420C stainless steel black blade and a clip on the handle. Measures 5″ closed and 8.5″ overall.
