When Cold Steel developed the Code 4, the goal was simple: create an ultra-thin, ultra-light folding knife that delivers serious performance without unnecessary bulk. Designed with everyday carry in mind, the Code 4 is built to disappear in your pocket while still offering the strength and reliability you expect from a hard-use utility knife.

Trusted by many in Law Enforcement and EDC enthusiasts alike, the Code 4 is the kind of knife you carry once and never want to replace.

Ultra-Light, Low-Profile Carry
Weighing just 4.3 oz with a slim profile, the Code 4 is easy to carry all day without weighing down your pocket or gear setup.

Premium American S35VN Blade Steel
The 3.5″ blade is crafted from American CPM S35VN stainless steel, known for its ability to take a razor-sharp edge and hold it through extended use.

Tanto Blade Configuration
The tanto blade profile offers added tip strength and controlled cutting performance, making it well suited for utility tasks and hard use.

Hard-Anodized Aluminum Handle
The handle is made from hard-anodized gunmetal gray 6061 aluminum, providing durability, rigidity, and a clean, understated look while keeping weight to a minimum.

Tri-Ad Lock Reliability
Cold Steel’s world-renowned Tri-Ad Lock delivers exceptional strength, shock resistance, and finger protection, giving you confidence during demanding cuts.

Ambidextrous Carry and Control
Ambidextrous thumb studs and a reversible pocket or belt clip make the Code 4 easy to deploy and carry no matter your dominant hand or setup.
