This knife was specifically designed to meet the needs of federal employees and individuals who have restrictions on carrying larger blades in certain buildings. It is a compact and easily concealable folding knife that serves both as a practical tool for everyday use and as a backup weapon in environments where carrying weapons is not allowed. The knife features a clipped Wharncliffe blade style, which is known for its excellent edge retention. The blade is made of CPM-M4 steel, which supports the ultra-fine point of the blade. This design allows the knife to focus all of its cutting force on the needle-thin tip, making it effective for both utility tasks and self-defense purposes. To enhance its usability, the knife comes with an included lanyard that extends the handle. This provides a full grip and easy access to the knife. Additionally, it is worth noting that the Immunity knife was conceived, designed, and developed entirely during the pandemic, hence its name.
