Though it is made out of aluminum, this fountain pen and ballpoint combo pen is not meant for personal defense. But the fact that it blends two writing tools into one makes it truly “tactical” to me. There is a medium nib fountain pen as your primary instrument with a ballpoint hidden under the butt end. Both tips can be posted. The ink cartridges used are short Pelikans while the ballpoint refill is a Diplomat specialty. If you like the idea of this pen, you might want to stock up on them. They last as long as a Parker refill, but your local office stuff dealer will most likely not carry them. Overall, it is a finely crafted pen, the general design being modern and timeless. Fountain pen it is first, with the ballpoint function reserved for “emergencies”. If you like this idea of minimizing the number of writing tools you carry, I highly recommend the Twingraph.
