Unboxing the QSP Viper: A Blade That Commands Attention

The first impression of the QSP Viper Fixed Blade Knife is nothing short of impressive. From the moment it leaves its packaging, it exudes craftsmanship, control, and calculated design. The black G10 handle contrasts sharply with the black stonewashed blade, giving it a tactical yet refined appearance — a visual statement of power and purpose.

This knife doesn’t just sit in your hand; it belongs there. The ergonomic curves, the textured G10 scales, and the sturdy finger choil all blend into one cohesive form that balances precision with control. Whether you’re an outdoor enthusiast, a survivalist, or a tactical user, the Viper’s design feels intuitive and deliberate.

Crafted to Perform: The Power of 10Cr15CoMoV Steel

At the heart of the QSP Viper lies its 4-inch trailing point blade, forged from 10Cr15CoMoV stainless steel — a material often compared to VG10 for its superior edge retention and durability. The steel’s composition provides a fine balance between hardness and toughness, allowing the knife to handle slicing, piercing, and delicate cutting tasks with ease.

The flat grind ensures a consistent, razor-sharp edge, while the black stonewash finish not only enhances the aesthetic but also provides added protection against wear and corrosion. Whether you’re cutting rope, preparing wood, or handling field dressing, this blade performs with confidence and control.

Ergonomics Redefined: The G10 Handle That Grips Back

The black G10 handle is a masterpiece of form and function. Heavily textured yet comfortable, it provides a secure grip even in wet, muddy, or gloved conditions. The contours of the handle fit naturally into the hand, accommodating multiple grip styles without compromise.

A large finger choil offers fine control for detailed work, while the pinky ring at the end of the handle opens up combative or reverse-grip handling. This adaptability makes the Viper ideal for both utility and tactical use — from bushcraft to defense applications.

A Knife with Two Personalities: Utility Meets Defense

One of the standout qualities of the QSP Viper is its dual-purpose design. It effortlessly transitions between a workhorse tool and a self-defense companion. When choked up on the choil and using the jimping for stability, it becomes a precision cutting instrument capable of detailed outdoor or utility work.

Flip the knife and engage the pinky ring, and it transforms into a tactical weapon that’s quick, responsive, and ready for close-quarters defense. This balance between utility and readiness makes the Viper not just a knife — but a complete survival solution.

The Kydex Sheath: Durability Meets Accessibility

No great knife is complete without a reliable sheath, and the QSP Viper doesn’t disappoint. It comes equipped with a Kydex belt sheath that’s both rugged and functional. The sheath provides secure retention, ensuring the knife stays firmly in place, while allowing for quick, smooth deployment when needed.

Lightweight and well-fitted, the sheath complements the Viper’s overall compact design, making it easy to carry for daily use, outdoor expeditions, or concealed tactical setups. The weight with the sheath totals 6.91 oz., maintaining a perfect balance between portability and reliability.

Every curve and contour of the knife is purposeful. From the pinky ring’s control advantage to the choil’s ergonomic precision, the design reflects a deep understanding of what users demand from a reliable fixed blade. This isn’t just a knife made to look good; it’s one made to perform.
