Product Description

Most butterfly knives make you choose between a flipper and a cutter. The Benchmade Necron doesn't. Built around a premium CPM-S30V blade and an adjustable tungsten weight system that lets you dial in balance and feel to your exact flipping style, the Necron is the only Bali-Song on the market that's genuinely engineered — not just manufactured.

The Necron's 4.59-inch scimitar blade is ground from CPM-S30V stainless steel — a particle metallurgy powder steel developed specifically for cutlery, with a vanadium carbide structure that produces outstanding edge retention, significantly better corrosion resistance than standard D2 or 440C, and a toughness profile that holds up under the mechanical stress of repeated flipping. Heat-treated to 58-60 HRC, it sits in the ideal performance band: hard enough to hold an edge through demanding cutting tasks, not so hard that it becomes brittle under impact. The flat grind maximizes edge geometry across the blade's full width, and the Blackwashed finish eliminates reflective signature while adding a layer of corrosion protection to the blade face. The scimitar profile — an upswept, curved belly — concentrates cutting power toward the tip and provides the visual drama the Necron's design demands.

What sets the Necron apart at a mechanical level is Benchmade's adjustable and removable tungsten weight system built into the Ruby Red G-10 handle scales. Tungsten is one of the densest materials available for this application — small amounts create significant weight shifts. By adding, removing, or repositioning the weights, you shift the knife's balance point forward or backward, changing the swing arc, momentum, and aerial behavior of the handles during manipulation. Handle extensions are also removable, letting you further adjust overall length and feel. No other production Bali-Song offers this level of user-tunable precision.
