Boker Plus Knives CNC Milled Titanium Self Defense Tactical 45 Cal Pen P09BO089
5" overall. Designed by Rainer Wenning and knifemaker Thomas Braunagel. The "bolt action" mechanism and "click" open and close will make it difficult to put this piece down. Effective self defense tool. The Clip Integrated Design (CID) offers easy placement in the pocket and has minimal give, to provide a comfortable draw resistance in normal tactical or denim pants pockets. CNC milled titanium construction. Not a firearm. Compatible with LAMY #M22 ink refills.
