Product Description

The Counterpart™ Blackout (K431KKP) takes Ken Onion’s signature ergonomic design and pushes it into tactical territory. Engineered for those who demand a "no-fail" tool for both daily utility and demanding field tasks, this edition features a high-strength tanto blade and hard-wearing D2 steel. The "Blackout" aesthetic is more than just a look—it’s a commitment to low-profile, high-performance carry that minimizes glare and maximizes structural integrity.

The 3.38" tanto blade is forged from D2 tool steel, a high-carbon alloy celebrated for its extreme hardness and superior edge retention during heavy use. The tanto geometry provides a reinforced tip for exceptional piercing power, while the black oxide finish adds an extra layer of surface protection and a sleek, non-reflective finish. Deployment is surgical and smooth thanks to the integrated thumb disc and IKBS™ ball-bearing pivot system, offering a controlled opening that feels like a custom tool. The lightweight black glass-reinforced nylon (GRN) handle is sculpted for a secure, fatigue-free grip and houses the fully ambidextrous Crossbar Lock for total control.
