Slipjoint Knives: Classic Elegance and Functionality

Presented at the 2019 Shot Show, Key is Viper's first dorsal spring slip-joint. Designed by Jesper Voxnaes, this closable with two-handed opening is a daily luxury to be savored without haste, a daily companion like a classy pen or a watch of fine manufacture.

The Key is offered in different handle variants, with details ranging from tradition to modernity, with or without insignia, in order to blend in with the style of its owner.

All have in common the refined hand-made filework that decorates the spring, giving the knife the typical, surprising, elegance that has always distinguished Viper “Gentleman” knives. The 3 mm thick, satin-finished Böhler M390 steel blade offers excellent and long-lasting cutting performance, accentuated by full bevel.
