Innovative tactical pen in the Böker Plus lineup, made from lightweight yet sturdy aluminum. The black anodized handle body and the sturdy cap are provided with checkering that provides grip without unduly stressing the pocket hem. The Böker Plus Tactical Pen also features a hard, rounded stainless steel insert at the end of the shaft, allowing it to be used as a kubotan. The cap features a precise screw thread and is additionally secured by an internal O-ring. For writing, the cap can optionally be simply attached to the back of the pen. Please note that the pen is unscrewed for lead replacement using a left-hand thread.! This prevents the pen from accidentally disassembling when unscrewing the cap
