When developing the Cold Steel Code 4, their aim was to create an ultra-thin, ultra-light, highly functional utility knife that is a breeze to carry. There is great comfort to be gleaned from knowing you are carrying a good knife, and Cold Steel believes that their Code 4 won?t weigh down your uniform or provide unnecessary bulk. It?s a pleasure to carry - so it?s always there when you need it. Available in a variety of blade configurations, with ambidextrous pocket clips and thumb studs, each Code 4 features sturdy, hard-anodized gun metal grey 6061 Aluminum handles, our world-renowned Tri-Ad locking mechanism, and high satin polished, razor sharp S35VN blades.
