Note: The originally presented version with Charcoal Grey handle scales was never realized; its successor is Crater Blue. The idea behind the Immunity was developed during the long phase of the pandemic - hence its name. The goal was to fulfill the frequently expressed wish of US government officials for a lightweight, compact EDC knife well suited for self-defense, without exceeding a blade length of 2.5 inches. Exceeding that blade length leads to a carry ban in many places in the USA.
For this reason, the Wharncliffe blade was the first choice. By using a Cerakote-coated CPM-M4 carbon steel blade, the full cutting power could be carried all the way to the needle-thin ground tip of the blade.
The anodized 6061-T6 aluminum handles are available in three interesting colors: Crater Blue, Flat Dark Earth, and Woodland Green. These help the Immunity look very good despite its rather short Wharncliffe blade. The Axis-Lock mechanism can be ordered as a manual or automatic version, so six versions are currently offered with the 2.49 inch blade. When pulling the Axis bolt, the blade of the automatic version opens very comfortably and safely. A lanyard at the end of the handle is included with all models and makes it easier to draw the knife, which is carried with a mini deep-carry clip.
