The Fenix T6 Tactical Pen is a perfect blend of self-defense, practicality, and writing capability. It features an 80-lumen LED with USB-C rechargeable power on the opposite side of the pocket clip, allowing for convenient attachment and illumination of work areas. The light is also detachable from the pen for additional convenience. Additionally, the pen has a glass-breaking tip fitted with a tough silicon nitride bead for emergencies and self-defense. It also rotates to reveal a Schmidt 6.8cm metal ink cartridge, allowing for smooth writing and providing an added self-defense option. Plus, it's TSA-compliant and highly portable, making it an ideal EDC tool. 

*Note: The T6 pen uses a Schmidt 6.8cm metal ink cartridge (Schmidt 635M ISO 12757-2D D1).
