THE DESIGN CONCEPT: THE APEX PREDATOR IN YOUR POCKET

Named after one of nature’s most lethal hunters, the Gryvex Viper (Model S3301) was born from a simple yet radical design philosophy by legendary custom designer Rattlesnake: To pack the heavy-duty breaching power of a full-sized tactical knife into a legal, everyday-carry footprint.

We wanted a blade that looks aggressive, feels like an extension of your hand, and performs without compromise under the most demanding tasks. The Viper doesn't just cut; it dominates.

WHY THE VIPER DOMINATES YOUR EDC ROTATION

Compact Powerhouse (The 2.9" Golden Ratio)

Featuring a 2.9-inch blade, the Viper is precision-engineered to be legally compliant in most strict U.S. jurisdictions without sacrificing an ounce of capability. With a massive 4mm (0.157") blade thickness, this "Little Monster" offers an aggressive flat grind that handles heavy-duty piercing and slicing with absolute confidence.

Apex Steel — Böhler M390

Forged from premium Austrian Böhler M390 steel (HRC 60±1) with a rugged stonewashed finish. It provides world-class edge retention, extreme wear resistance, and near-immune corrosion resistance. Less time sharpening, more time deploying.

Titanium Armor with Lightning Strike Finish

The handle is CNC-machined from solid 6Al4V Titanium, providing an indestructible yet lightweight chassis (only 108g). The mesmerizing Lightning Strike Finish ensures that no two knives look exactly alike—giving your gear collection a distinctive, high-end custom aesthetic.

Viper-Fast Hydraulic Deployment

Equipped with a Caged Ceramic Ball Bearing pivot assembly, the manual deployment via dual stainless steel thumbstuds is crisp, rocket-fast, and hydraulically smooth.

The Vault-Like Frame Lock

Safety is non-negotiable. The beefy Titanium Frame Lock ensures a rock-solid, zero-play lockup. When the Viper clicks open, it feels like a fixed blade dagger in your hand.
