Cold Steel Hell Butterfly Knife Black Aluminum Handle Black PS CPM S35VN Stainless Steel Blade CS-CS-FL-46HLL

Cold Steel pushes performance to the edge with the Hell Butterfly Knife, a purpose-built butterfly knife engineered for strength, speed, and precision. Designed for serious users who expect their gear to perform without hesitation, this knife combines premium materials with clean, functional construction. Every detail reflects Cold Steel’s commitment to durability and real-world capability.

The 4 5/8-inch blade is crafted from CPM S35VN stainless steel, a high-performance powder steel known for its exceptional edge retention, toughness, and corrosion resistance. It’s the kind of steel that holds a razor edge through repeated use and won’t back down when the work gets demanding. Finished in a black coating and featuring a PS profile, the blade delivers an aggressive look backed by dependable cutting performance. Whether you’re practicing transitions or putting it to task, the blade maintains the balance and strength you expect from top-tier materials.

At 10 1/8 inches overall, the Hell Butterfly Knife offers full-size handling with impressive control. The 5 1/2-inch black aluminum handles are precision-machined for strength while keeping weight down to just 3.3 ounces. That lightweight build makes a noticeable difference during extended flipping sessions, allowing quicker movement and reduced fatigue without sacrificing structural integrity. The aluminum construction provides a solid, confident feel in hand while maintaining smooth rotation and consistent action.

Cold Steel engineered this balisong for fluid performance. The balance between blade and handle ensures clean rollovers, steady momentum, and reliable control. It’s responsive without feeling loose and solid without feeling heavy. That harmony between materials and design makes it suitable for experienced flippers and collectors who appreciate refined mechanical execution.

The Hell Butterfly Knife stands as a premium addition to Cold Steel’s lineup. It’s built for those who understand that performance starts with materials and ends with precision engineering. From the black-coated CPM S35VN blade to the lightweight aluminum handle construction, every component works together to deliver a knife that looks aggressive and performs with authority.
