The CIVIVI Sentinel Strike II in black aluminum is a flipper and thumb stud folder with a 3.7-inch Nitro-V steel drop point blade and a button lock (brand part no. C22025D-1). The blade is black stonewashed and ground with a hollow primary bevel and a flat ground tip. The handle is machined aluminum with a black FRN integral back spacer, and a glass breaker tip on the end adds an emergency tool to the carry. A caged ceramic ball bearing pivot gives a smooth, fast deployment. At 3.69 ounces it is substantial enough to feel secure in hand and still light enough for everyday carry.
