Heibel Menace Balisong #21 Black Stonewash Damasteel/Black Coated Titanium HKM021

Built for precision, control, and relentless flipping performance, the Heibel Menace Balisong #21 is a no-nonsense design that captures the raw energy behind balisong culture. Butterfly knives aren’t about simple utility—they’re about fluid motion, timing, and the skill it takes to keep everything moving in perfect rhythm. This model is dialed in to deliver exactly that.

At the center is a 5.5" Damasteel blade with a black stonewash finish, blending rugged durability with a bold, low-profile look. The layered steel pattern adds depth beneath the darkened surface, giving the blade a distinctive character that stands apart from standard finishes. Paired with black coated 6Al-4V titanium handles, the Menace #21 keeps things stealthy while maintaining exceptional strength and lightweight performance.

The channel, tapered handle construction enhances balance and control, allowing the knife to move naturally through complex flipping sequences. Tang pins provide reliable, consistent operation, while the stainless steel bushing system combined with phosphor bronze washers ensures smooth, stable action with every rotation. TiConnector stainless steel pivots with T8 Torx hardware round out the build, offering durability and precise tuning.

Weighing in at 4.8 ounces and measuring 10.35" overall, this balisong strikes a solid balance between momentum and agility. It feels substantial enough for controlled manipulation without sacrificing the responsiveness needed for fast transitions.

Proudly made in the USA, the Menace #21 reflects a commitment to high-end craftsmanship and performance-driven design. It’s available at Smoky Mountain Knife Works, the world’s best online knife store and a true Tennessee landmark. Nestled in the heart of the Great Smoky Mountains, SMKW draws over 1.5 million visitors each year to its legendary showroom, making it a destination every knife enthusiast should experience.
