CRKT James Williams Tactical Pen TPENWK is a stylish writing instrument designed with all of the fine qualities you would expect in a nice pen, but it's more than that. Former Army officer and martial arts instructor James Williams applied his design expertise to this CRKT 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, the Columbia River Williams 6061 Aluminum Tactical Pen offers long lasting durability and toughness. Columbia River Knife and Tool has made the Williams pen available in non-reflective tactical black finish, and 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 the Columbia River Knife & Tool James Williams Black Self Defense Pen also makes for a great writing instrument.
