BUILT TO WRITE FOR YEARS
The barrel is hollowed from a single block of aluminium alloy, then finished in HA3 mil-spec coating that shrugs off stains and corrosion. It keeps its looks in a shirt pocket, a glovebox or the bottom of a work bag, and the slim 0.95cm profile sits comfortably in the hand for long notes.
A BOLT ACTION YOU WILL WANT TO USE
The bolt action lever is modelled on a rifle bolt and chambers the tip with one thumb from either side, so left and right handers both get a clean throw and that crisp aluminium click. It deploys and retracts the point in one motion, which keeps the tungsten tip protected in your pocket until the moment you write.
A TIP THAT GETS YOU OUT
The tapered tip is made from ultra-hard tungsten steel, the same material that lets it break non-tempered glass such as a car side window. It rides retracted and out of the way during everyday writing, then becomes a self-defence and escape tool the instant you need one, all from the pen already clipped to your pocket.
REFILLS YOU CAN ACTUALLY FIND
It writes with a black German made Schneider Gelion 39 cartridge out of the box, and it accepts a wide range of common refills, so topping up the ink is easy wherever you are. That makes it a smart pen to keep for the long run, and a considered gift for anyone who appreciates good kit.
WHY THE NTP31 OVER AN ORDINARY PEN
Machined metal, not moulded plastic
A solid aluminium alloy body with a HA3 mil-spec finish takes daily knocks where a plastic pen cracks or stains.
A tip that breaks glass
The tungsten steel point doubles as a window breaker and escape tool, something an ordinary pen will never do.
Bolt action both ways
A two-sided bolt lever deploys the tip with a satisfying click, where a click-pen feels flimsy by comparison.
Easy to keep writing
Standard Schneider refills and wide compatibility mean ink is simple to replace, instead of binning the whole pen.

What ink refill does it use, and can I swap it?
It comes with a black German made Schneider Gelion 39 cartridge, and it is compatible with a wide range of common refills. When the ink runs low you can fit a fresh Gelion 39 or one of the other refills it accepts, so you keep the pen and just change the cartridge.
Can I take it on a flight?
The NTP31 is a pen with no liquids or batteries inside, which makes it safe to carry in everyday air travel. It is a handy companion for filling in landing cards and customs forms once you arrive.
Does the bolt action work for left-handers?
Yes. The bolt lever chambers the tip from either side, so left and right handers both get the same smooth throw and crisp click with a single thumb.
