If you want your writing instrument to be tough, effective and serve as a defensive tool in a tight situation, the Hinderer Investigator Pen in black is a good choice. Designer Rick Hinderer is known for both his artistic knives and his tactical masterpieces, and the Investigator Pen combines a bit of both his talents. Longitudinal grooves on the barrel and ridges around the ends give you excellent grip while the small bullet point on the pen's back unscrews if you choose to add a different type of attachment.
The Investigator Pen in black is made from aircraft grade 6061-T6 aluminum and protected with a military-grade anodized coat. Each pen is CNC machined in the U.S.A. For writing excellence, the pen uses Fisher Space pen refills. It measures just 4-3/8 inches and weighs less than an ounce so you can take it almost anywhere. The Investigator pen works well for field notes because of its durability.
