WHAT IS A BOLT ACTION PEN?

A bolt action pen is simply where the bolt on the side of the pen is used to push a refill cartridge down and lock it into place. It's an incredibly reliable mechanism and just as satisfying to click into place. A well-made bolt action pen can withstand millions and millions of cycles and last more than a lifetime.


WHAT MAKES OUR PEN SO UNIQUE?

It’s Adjustable

Our pen is the first of its kind. You can adjust the ink tip to extend closer or farther from the pen’s tip. This allows you to fine-tune your pen to fit your personal writing style. Extend the tip longer for a more slanted writing style. Retract the tip tighter for a more vertical writing style.

IT'S VERSATILE

Our pen’s unique feature that allows you to adjust the tip length also enables the pen to accommodate nearly any standard ink refill. It can hold ink refills from 89mm to 116mm in length, which includes the overwhelming majority of full-size refills on the market. This includes popular ink refills like Fisher Space Pen, Pilot G-2, and many more.


Our Modern Fuel Bolt Action Pen comes standard with a Pilot G-2 refill already fitted.

It’s Minimalist

Many bolt action pens are designed to look large and bulky, but our Bolt Action Pen is ⅜” (9.5mm) in diameter, considerably thinner than most bolt action pens on the market today.


Our slimmer, sleeker, minimalist take on the concept is more comfortable to hold and easier to carry.

A PURPOSE FOR EVERY PART

Everything we make at Modern Fuel has an enduring quality thoughtfully built into every part. No hidden plastic parts beneath the surface, solid metal parts made on a swiss lathe built to flawlessly perform their duty and last a lifetime.


HOW IT'S MADE

First, the cone and the body are cut out of a solid block of premium metal independently. This gives us the overall shape of the pen and parts we can now work with. The two parts are assembled. It's an impressively snug fit, but not quite up to our standards.


The pen and the cone are then sent through the Swiss Lathe for a high-speed pass. This removes any seam between the two, effectively mating that pair. No other cone will fit a body quite like the one it was mated with. The pen is then hand-polished and inspected.

MEET THE METALS

BRONZE

Luxury watch grade bronze

Bronze has long been used as a durable metal for ship fittings and diving equipment. We’re the only pen out there that uses a solid piece of C52100 bronze, a high quality bronze often reserved for high-end luxury watches. Bronze has a significant weight to it, the user can truly feel the stable balance and all-metal construction. The bronze pen will have a matte patina over time as it ages. Choose bronze if you’re looking for a softer metal that ages with character offers an antique feel.

COPPER

VINTAGE HEIRLOOM FEEL

Copper has a distinct look and feel that ages with character. Often used for high end home finishings like faucets. Copper is a softer metal that will embody its usage and patina over time. For the discerning user looking for a pen with heft, copper is our heaviest pen. Choose copper if you’re looking for a distinct metal with heft that ages with the user for a beautiful antique heirloom piece.

STAINLESS STEEL

SLEEK, LOW-MAINTENANCE ELEGANCE

Stainless steel is a hard metal with excellent resistance to corrosion. It is one of the most common metals used in luxury watches for a highly practical clean, sleek look. The pen is heavy enough to feel the heft of quality, but not too heavy. It will not dull or patina over time, leaving you with the same pristine pen for decades to come. Choose stainless steel if you want a moderately heavy pen that will look as good as new in 50 years.

TITANIUM

Unparalleled strength

Titanium is as hard as steel and 45% lighter. Unaffected by fatigue, cracking, aging, or corrosion. Titanium is trusted for the toughest jobs on the planet, including use inside jet engines. The titanium pen is the lightest pencil by far. Choose titanium if you want a light, nearly indestructible pen that will withstand even the harshest conditions and still look brand new.
