Yue Dong Design, Ultra-Slim S90V Precision EDC

The Porcupine has always been built for real work—slicing, cutting, and handling detailed everyday tasks with confidence. Bringing Vosteed's ultra-thin TiSlim concept to a proven platform, the Porcupine TiSlim is engineered with an exceptionally thin 0.315" profile that carries light and easy in the pocket. Featuring Grade 5 titanium handles with an acid-washed copper finish, it provides high structural rigidity with a sleek aesthetic. The 3.04" drop point blade is upgraded to CPM-S90V stainless steel with an acid wash and stonewash finish, offering elite edge retention and wear resistance. Equipped with a Top Liner Lock for smooth, safe button-actuated closing that keeps fingers out of the blade path, it deploys effortlessly via dual thumb studs riding on caged ceramic ball bearings.
