At first glance, this is an ordinary pen, but in fact, it has hidden tactical functionality. The body is made of aircraft-grade aluminum, which is highly durable and non-corrosive. A special clip allows carrying a pen not only in a bag or backpack, but also to fasten it in a pocket or on equipment. The tip on the back of the handle is equipped with cullet, which can be used for tactical purposes: breaking glass in emergency situations or for self-defense.
The Type 5 model writes really well. The opening and closing of the rod are due to the rotation of the body handle around the axis for clockwise and counterclockwise, respectively. The pen will write in the most extreme conditions. Therefore, if you are going on a hike or traveling, this is the best pen for recording all your notes. Also, the rod can easily be replaced with a new one when it runs out of ink.
