Product Description

The Cold Steel Frenzy II (Model CSFL35FRNBKBK) is a high-performance tactical everyday carry (EDC) folding knife designed by custom knifemaker Andrew Demko. Inspired by the Japanese Kabutowari, it features a 3.50-inch Wharncliffe/Sheepsfoot blade crafted from premium CPM-3V tool steel with a protective black DLC finish. Secured by Cold Steel's patented Tri-Ad® lock, the Frenzy II pairs extreme lock strength with an ergonomic black G10 handle, making it a lightweight yet extremely durable cutting tool.

The blade is CPM-3V tool steel, prized for exceptional toughness and impact resistance rather than pure edge retention, making it a strong choice for a knife you actually intend to work hard rather than baby. The Wharncliffe/Sheepsfoot profile, drawing on the traditional Japanese Kabutowari's straight-edge geometry, keeps the cutting edge in a straight line to the tip, reducing the risk of accidental tip breakage during hard use, while the black DLC/PVD finish adds a layer of corrosion resistance and a low-glare, tactical look.

CPM-3V High-Toughness Steel: Blade is forged from CPM-3V tool steel, offering superior impact resistance and edge holding to prevent chipping during hard use.
Andrew Demko Design: Sleek Japanese Kabutowari-inspired blade profile delivers exceptional piercing capability and razor-sharp slicing performance.
Tri-Ad® Locking System: Equipped with Andrew Demko's world-renowned Tri-Ad lock, engineered to withstand extreme shock, weight, and lock-failure stress.
Lightweight G10 Scales: Textured black G10 handles provide a secure, slip-resistant grip while keeping overall weight under 3 ounces for easy pocket carry.

Ideal for buyers who want a genuinely hard-use folder without stepping up to a fixed blade. Outdoor and duty users who want CPM-3V's toughness for batoning-adjacent or high-impact tasks a standard EDC steel wouldn't tolerate. Tri-Ad® Lock fans who want the mechanism in a lighter, more pocket-friendly package than Cold Steel's larger platforms.

A hard-use folder built to outlast the abuse most knives are designed to avoid. Add the Cold Steel Frenzy II (CSFL35FRNBKBK) to your cart today and experience Tri-Ad® Lock strength backed by Cold Steel's Limited Lifetime Warranty and the fast shipping Knifeworks is known for.

Cold Steel Frenzy II: Frequently Asked Questions

Common questions about the Cold Steel Frenzy II folding knife, answered by the Knifeworks team.

Why does the box label say "Frenzy" instead of "Frenzy II"?+

Cold Steel uses unified packaging for the entire Frenzy family, printing "FRENZY" as the overall series title on the physical box artwork. Retailers label this specific model as the Frenzy II to differentiate this compact 3.5-inch version from the original 5.5-inch model. You can verify your exact knife by checking the end-flap barcode label for item number CSFL35FRNBKBK.

Who designed the Cold Steel Frenzy II?+

The knife was designed by custom knifemaker Andrew Demko, who also invented Cold Steel's signature Tri-Ad locking system.

Is CPM-3V steel stainless?+

CPM-3V is a high-toughness tool steel, not a true stainless steel. However, the black DLC (Diamond-Like Carbon) coating on the Frenzy II provides exceptional surface protection against corrosion and wear under everyday use.
