CRKT Williams Tactical Pen: Low Profile, EDC Self Defense Survival Pen Made of Black Anodized Aluminum with Pressurized Ink Cartridge and Pocket Clip TPENWK;

To everyone else they're stylish writing instruments designed with all of the fine qualities you would expect in a nice pen, but to you they're more than that. Former Army officer and martial arts instructor, James Williams applied his design expertise to the Williams tactical pen. For those of you familiar with the Hissatsu and the Hisshou, this new James Williams design is sure to be a welcome addition to your defensive edged tools.

A clean, futuristic interpretation of one of mankind's basic tools, the tactical pen is a high-tech writing instrument that can be used as a self-defense enforcer if need be. Made from precision-machined aluminum and hard-coat color anodized, they offer long lasting durability and toughness. Available in non-reflective tactical black finish. The tapered body improves grip while adding a contemporary look.

With some basic instruction or knowledge, one can readily use the pens against an assailant or attacker to inflict notice, pain or injury-thwarting an otherwise potentially defenseless act.

And, they're just plain great writing instruments as well.
