The new Jesper Voxnaes designed Viper Key is a modern traditional slip joint with clean lines, a slim profile and high performance materials that make it an outstanding choice for users and collectors alike. This version comes with a crowned and satin finished Bohler M390 blade, titanium bolsters and Carbon Fiber handle scales.

Brand new, direct from Viper Knives. Made in Italy.

Blade: The slim drop point blade is made from Bohler M390 which has been fully flat ground and satin finished. Opening with a solid half stop, the blade operates just like a traditional slip joint and opens via a generous nail nick. The clean, crowned spine flows right into the handle and is one more accent on this gentleman's modern traditional. The Key will open envelopes, fruit and packages with ease in addition to tackling other EDC cutting tasks.

Handle: Solid titanium liners support integral titanium bolsters that are flush fit to matte finished Carbon Fiber handles that have been contoured to deliver a highly comfortable in-hand feel. Subtle finger grooves and a pinkie hook deliver a solid grip while still having elegant, sweeping lines. The back spring is strong for security while still being smooth to operate and has beautiful file work enhancing the aesthetic. A generous hole is provided for lanyard attachment.

Sheath: Carries in a stitched leather slip sheath. No pocket clip.

Bohler M390: Bohler M390 has become an extremely popular choice for high-end user grade knives thanks to its extreme edge retention. M390 also has a good corrosion resistance, meaning most users can avoid problems by simply wiping off their blade after each use. Another great feature of this steel is its ability to resist burr formation during sharpening. Comparable steels are CTS-204P and Duratech 20CV.
