That has a fire striker, whistle, breaker tip and D1 cartridge.
It looks like too much in the same object, and I wonder how it is to write with. That being said, it would nicely fit in my EDC and cover the need for emergency fire, writing, and noise making (I have three kids and work in a summer camp every year, and that whistle might come in handy more than you would imagine…
Anyone satisfied with that pen ?
There is a youtube about them, but I wanted YOUR enlightened opinion…
