NITECORE NTP31 is a uniquely designed aluminium alloy bolt action tactical pen. The three position bi-directional bolt action allows you to pop out the pen tip or window breaker, or retract both for everyday carry. The NTP31 houses an easily replaceable Schneider gel ink refill for quick drying, waterproof, and fade resistant writing. On the other end of the NTP31 is a tapered tungsten steel point window breaker. Tungsten steel’s hardness is only second to diamonds.

The NTP31 is constructed from aluminium alloy that offers lightweight ruggedness with an excellent resistance to impact and corrosion. The NTP31 is designed to be used outdoors and is perfect to withstand harsh conditions.

Designed for comfortable writing, the body of the NTP31 has anti-skid threads in the centre which increases friction and prevents sliding. A strong stainless steel clip allows you to easily attach the pen to your pocket, shirt, or backpack to avoid the loss of the pen. Weighing only 20.41g and measuring less than 14cm in length, the sleek NTP31 is the perfect addition to your EDC collection or survival gear toolkit.

  • High quality German ink refill for quick-drying, waterproof, and fade-resistant writing.
  • Lightweight with Stainless steel clip for secure carry

    Awesome pen .
    in love with it

    I’ve been familiar with Nitecore for sometime, having used their torches for both utility, hunting, and security. As far as pens go, this is a winner. This is the third “tactical” pen in my collection and by far my favourite. One thing that bugs me about tactical pens is they are typically quite large, which is not the case here. Sleek and simple, the two way bolt action is great, it’s super comfortable, the ink cartridge is great quality. My go to used to be Rite in the Rain, but this wins hands down for both functionality and style.

    I can now write all my favourite words while smashing a window! What more could a girl want? Maybe I’ll start a window repair business with hand written cards…

    I have had a lot of good pens over my time, but I have to say that the NTP31 is probably the best pen I’ve ever had. It is comfortable to write with, looks good and just works perfectly every time. I’m so impressed, I’ve just purchased the Titanium version. Nitecore really make very good pens, as well as torches.
