Description
SureFire built its name on flashlights that survive the real world, and the Pen IV carries that same reputation into something you'll use every single day. This is a serious writing instrument machined from high-strength aerospace aluminum and finished in a Type III hard-anodized black coating, the same tough treatment you'll find on a lot of SureFire gear. At 5.8 inches long and right around 1.7 ounces, it has a solid, balanced heft in the hand that makes writing feel deliberate rather than flimsy.
What Sets the SureFire Pen IV Apart
Inside the machined body sits an imported Schmidt easyFLOW 9000 ballpoint cartridge, which is a favorite among pen people for a reason. It lays down ink smoothly with a consistent flow, so you're not scribbling circles to get it started on a cold morning. The ink tip retracts fully into the body, which means there's no cap to lose and nothing exposed to snag or dry out in your pocket.
Hardware Built to Match the Body
The stainless steel hardware carries a diamond-like coating on the pocket clip and nose cone, with a black oxide treatment on the retractor button. The clip is heavy-duty and holds tight, so it stays put whether it's riding in a shirt pocket, a pack strap, or a pouch. Everything about the fit and finish feels dialed in, which is what folks have come to expect from the brand.
Everyday Carry That Earns Its Keep
This is a pen you can toss in a bag, drop in a jacket, or clip to a notebook and forget about until you need it. It's assembled in the U.S.A. with that imported Schmidt cartridge doing the writing. If you appreciate gear that outlasts the cheap stuff and feels good in the hand, the Pen IV fits right in alongside the rest of your well-made kit.

Frequently Asked Questions
What kind of ink cartridge does the SureFire Pen IV use?
The Pen IV comes loaded with an imported Schmidt easyFLOW 9000 ballpoint cartridge. It's a well-regarded refill known for smooth, consistent ink flow. Since the Schmidt 9000 is a standard aftermarket cartridge, you can pick up replacements when it eventually runs dry.
Does the SureFire Pen IV have a cap or is it retractable?
It's a retractable design, so the ink tip pulls back into the body when you're done writing. That means there's no cap to misplace and nothing exposed to catch on your pocket. A press of the retractor button deploys the tip when you need it.
What is the Pen IV made of and how durable is it?
The body is machined from high-strength aerospace aluminum and finished with a Type III hard-anodized coating, which is the same rugged treatment SureFire uses on much of its other gear. The pocket clip, nose cone, and retractor button are stainless steel. It's built to handle daily carry and hold up far better than a typical office pen.
How big and heavy is the SureFire Pen IV?
It measures 5.8 inches long and weighs about 1.7 ounces. That gives it a solid, balanced feel in the hand without being cumbersome. It carries easily clipped to a pocket, notebook, or pack.
