Viper Key Carbon Fiber with Bolsters V5978FC

The Viper Key Carbon Fiber with Bolsters is a modern gentleman’s knife that doesn’t sacrifice grit for elegance. Built in Italy with clean lines and premium materials, it’s a rugged everyday carry that’s as capable in the field as it is refined in the hand. This isn’t a flashy folder—it’s a purpose-built tool wrapped in sophistication, made for those who expect performance in a compact, low-profile package.

The 3" Bohler M390 stainless steel blade is the star of the show. Known for its excellent edge retention, corrosion resistance, and wear toughness, M390 is one of the most sought-after steels in high-end production knives. The satin finish adds a clean, functional aesthetic, while the classic drop point shape offers versatile performance for slicing, detail work, and everyday cutting tasks. A traditional nail nick keeps the look understated while allowing for controlled, two-hand opening.

Closed, the knife sits at 4.25" and disappears easily into the pocket, with a weight of just 2.33 ounces—light enough to forget until you need it. The carbon fiber handle scales bring strength without bulk, offering a modern texture that pairs seamlessly with the polished stainless steel bolsters. It’s a combination that feels both tactical and tailored, ready for hard use or a night out.

Inside, bronze washers keep the action smooth and reliable, while a fileworked backspacer adds a touch of old-world craftsmanship to an otherwise minimalist build. The lanyard hole gives you carry options or room for a quick-access pull—because good design never forgets function.

The Viper Key is made for those who appreciate the balance of modern materials and timeless design. Whether you’re slicing fruit, opening packages, or prepping gear at camp, this knife brings consistent, reliable performance with a refined edge. It's not about size or flash—it’s about quality, feel, and how well a tool works when you need it most. Order it today from SMKW!
