The Fisher Measure Twice Tactical Bolt-Action Space Pen is built for pilots who need one tool that writes anywhere and doubles as an emergency egress aid. It pairs the pressurized Fisher Space Pen cartridge with a machined bolt-action body and a hardened glass breaker tip, so it earns its place in a flight bag, a uniform pocket, or a go-bag.
Writes when an ordinary pen quits
The sealed, pressurized cartridge does not rely on gravity. It writes inverted, at altitude, in the cold, through humidity, and on damp paper, which is exactly the situation you hit copying a clearance on a rain-soaked ramp or filling out a logbook upside down in a climbing turn. Fisher rates the cartridge from -30F to 250F.
Bolt-action deployment, one hand
The bolt-action mechanism opens and closes with a single thumb stroke and locks positively in both positions. There is no cap to drop in the footwell and no click-top to fire off in your pocket. You can deploy it while your other hand stays on the yoke or the checklist.
Glass breaker tip
The pen terminates in a hardened striking point designed to shatter tempered glass. It is a last-resort tool, not a party trick, and it is the reason this pen belongs in an aircraft, a vehicle, or a ditch bag rather than a desk drawer.
Built to be carried
Machined construction, a pocket clip, and a compact profile mean it rides comfortably clipped to a shirt pocket, a kneeboard, or a flight bag organizer panel. Refills use the standard Fisher pressurized cartridge, so it stays in service for years rather than being thrown away.
Who it is for
Pilots and crew who want one pen that works in every cockpit condition, instructors who write constantly in awkward positions, and anyone building a serious everyday-carry or emergency kit. It also makes a genuinely useful gift for a pilot who already owns everything decorative.

Frequently Asked Questions
How is this different from a standard Fisher Space Pen?
It uses the same pressurized Fisher cartridge, but adds two things a standard Space Pen does not have: a bolt-action mechanism you can work with one hand, and a hardened glass breaker tip at the base for emergency egress. The writing performance is identical, the carry role is not.
What temperature range can it write in?
Fisher rates the pressurized cartridge from -30 degrees F to 250 degrees F, which covers a cold-soaked ramp in winter through a closed cockpit sitting on summer asphalt.
Will it write upside down or on wet paper?
Yes. The cartridge is sealed and pressurized rather than gravity fed, so it writes at any angle, including inverted, and it will mark damp paper. That is the situation you hit copying a clearance in the rain or writing in a logbook held above you.
How does the glass breaker tip work?
The base of the pen terminates in a hardened striking point. Applied to the corner of a tempered side window with a sharp strike, it concentrates force in a small area to fracture the glass. It is an emergency egress aid for an aircraft or vehicle, not an everyday feature.
Can I take it on a commercial flight?
Pens are generally permitted in carry-on baggage, but tactical pens with a hardened striking tip sometimes draw scrutiny and the screening officer always has final discretion. Check current TSA guidance before you travel, and pack it in checked baggage if you would rather not risk it.
Can the pen be refilled?
Yes. It takes the standard Fisher pressurized cartridge, so it stays in service for years instead of being replaced. PilotMall carries a range of aviation writing tools. Browse our aviation pens collection for refills and alternatives.
