CIVIVI Knives Sentinel Strike Flippers

The Sentinel Strike series primarily uses K110 or Nitro-V steel, with select Damascus options also available for certain variants. K110 is a high carbon steel that offers excellent edge retention, while Nitro-V provides enhanced corrosion resistance and toughness. To understand how these materials perform in different environments, consult our Best Knife Steel Guide.

The Sentinel Strike series offers multiple deployment methods, including a flipper tab, dual thumb studs, and a blade cutout for thumb or reverse flicking. Because these knives utilize a button lock mechanism, you can also depress the lock button to swing the blade open or closed with a simple wrist motion.

The Sentinel Strike is remarkably light for its size, weighing approximately 3.5 ounces despite having a 3.7 inch blade. This lightweight construction is achieved through the use of aluminum handle scales and an injection molded FRN integral backspacer that keeps the overall weight down without sacrificing structural integrity.

The Sentinel Strike series offers two distinct blade shapes: an aggressive reverse tanto and a compound ground drop point. Both styles provide a high flat grind for efficient slicing geometry and include a generous sharpening choil that allows users to choke up for more controlled cutting. You can learn more about these styles in our Guide to Knife Blade Shapes.

Yes, the Sentinel Strike series includes a ball style glass breaker integrated into the pocket clip attachment screw. This feature provides additional utility for emergency situations without creating a sharp point that might cause discomfort while the knife is carried in a pocket.
