When developing the Cold Steel Code 4 our aim was to create an ultrathin ultralight highly functional utility knife that is a breeze to carry. It wont weigh down your uniform or provide unnecessary bulk. With an ambidextrous pocket clip and thumb studs each Code 4 features sturdy hardanodized gunmetal grey 6061 aluminum handles TriAd locking mechanism and high satin polished razor sharp American S35VN blades.
