Rike Knife-Viper 4

The Viper 4 continues the evolution of the Viper series with a sharper, more sculptural interpretation of the platform. Built around the same integral architecture and performance driven proportions, the Viper 4 distinguishes itself through a fully titanium presentation and an intricate new surface treatment that gives the knife a distinctly more aggressive character.

At the core of the design is a 3.35 inch blade crafted from Bohler M398, a premium powder metallurgy steel selected for exceptional edge retention, corrosion resistance, and long term cutting performance. With a robust 0.20 inch blade thickness, the Viper 4 maintains the same commanding structural confidence that defines the series. The blade geometry remains purposeful and performance oriented, delivering clean slicing capability within a bold, modern silhouette.

Where the Viper 4 truly sets itself apart is in the handle. Precision machined from a single piece of 6AL4V titanium, the integral frame is enhanced by detailed dragon scale micro milling on both sides. This intricate texturing adds visual depth, improved tactile grip, and a striking sense of movement across the body of the knife. Unlike the Viper 2, the Viper 4 forgoes carbon fiber inlays entirely, allowing the titanium construction and surface detailing to take full focus.

Offered in four colorways, the Viper 4 presents a more unified and technical interpretation of the Viper line. Each finish emphasizes the complexity of the milling while preserving the clean, aggressive geometry that gives the platform its identity.

Deployment is handled by a tuned flip tab, delivering fast, controlled action with a crisp mechanical feel. The frame lock engages with solid, dependable lockup, completing a design built for both performance and visual impact. At 3.17 ounces, the Viper 4 remains impressively lightweight for an integral titanium platform.
