Cold Steel Code 4 3.5in S35VN Folding Knife - Tough EDC Blade

In this review the Cold Steel Code 4 stands out as a compact, dependable everyday carry knife for users who want a blade that balances weight, strength, and edge retention. The single biggest reason to buy is its combination of a razor-sharp S35VN steel blade and the robust Tri-Ad locking mechanism, which together deliver a reliable tool for demanding daily tasks without weighing you down.

Key Features

• Ultra-thin, lightweight design: The slim profile and 4.3 oz weight make it comfortable to carry all day without drawing attention or creating bulk in a pocket.
• S35VN stainless blade: The 3.5in S35VN blade maintains a keen edge and tolerates heavy use, reducing the frequency of sharpening needed in the field.
• 6061 aluminum handles: Hard-anodized gunmetal grey 6061 aluminum provides a durable, corrosion-resistant grip surface that stands up to rough handling.
• Tri-Ad locking mechanism: Cold Steel's Tri-Ad lock offers outstanding strength and shock resistance so the blade stays secure under load.
• Ambidextrous carry features: The ambidextrous thumb studs and pocket clip let left- or right-handed users deploy and carry the knife comfortably.

Who It's For

The Code 4 is best suited for outdoorsmen, first responders, and everyday carry enthusiasts who want a strong, lightweight folder that can handle cutting, slicing, and utility tasks without fuss. Its sturdy construction and premium S35VN steel appeal to anyone who values long edge life and a solid lock for occasional heavy use.

Those who need the absolute lightest possible blade for minimalist carry or who require a dedicated tactical knife with specialized non-folding features might prefer a different tool. If you want an assisted-opening or larger fixed blade for extreme work, look elsewhere.
