A true tactical pen, the Tuff Writer Operation Series pen includes both a round and sharp end that can be used for defense, a stylus or even an emergency glass-break tool. Made of 6061-T6 aerospace-grade aluminum with a non-reflective sniper gray sanitized finish, the Operation pen incorporates external knurling for a great grip and a spring steel clip that won't snag coming in or going out of your pocket. The cap area includes a lanyard hole and is a bit wider and rounded to fit even better in your palm -- should you need to handle it that way. An included Fisher Space Pen Pressurized SPR4 cartridge lets you write from any angle. The Tuff Writer Operation Series pen, which is made in the U.S.A., measures 6 inches with cap and weighs 1.5 ounces; it comes with a Tuff Writer Protection Tube Pen Case.
