Civivi Synergy 4 C21018A-2

The original Synergy was designed by retired mechanical design engineer turned competitive shooter Jim O'Young and produced by CIVIVI's sister company WE Knives. Jim leveraged his knowledge and experience to design and engineer the SpeedTech Synergy folding knife using SolidWorks, a state-of-the-art, 3-dimensional, solid modeling CAD software tool. It was the very first knife created using this technology and featured several design elements never seen before in a production folding knife: an ergonomic, fully 3D digitally sculpt surface handle machined from a single, solid billet of material, a captive floating bearing system, and a button lock with increased engagement geometry. 

The Synergy4 is a larger version of the CIVIVI Synergy3. It has the same sleek look and killer action as its predecessor, but is a lot easier to get your hands on thanks to its more wallet-friendly materials, which are still top-performers in their own right.
