The revolutionary design of the "tactical" pen was created with the participation of Rainer Wenning - the designer of the SO4PRO-K kubotan. This pen is the essence of lightness and comfort of use. Turned and milled from a single piece of aluminum, it is strong enough to function as a kubotan. On the other hand - elegant anodization and low weight make it very comfortable to write with. An interesting fact is the latch blocking the cartridge, reminiscent of a rifle lock. Simple and effective to use, just like its military counterpart. A unique feature is the clip integrated into the pen casing. The clean form improves the comfort of writing, and the thick aluminum "clip" is much more resistant to stress than classic "wire" clips.
