OKNIFE B1 Lightning Strike Titanium EDC Pen | TC4 Titanium

A little lightning in your pocket. And yes, it writes, too.

The OKNIFE B1 Lightning Strike takes the compact, practical design of the original B1 titanium pen and gives it a striking new finish.

Precision-machined from TC4 titanium, the B1 features a distinctive Lightning Strike treatment that creates branching, fractal-like patterns in vibrant blues and purples. The result is a unique, eye-catching finish that feels smooth in hand while maintaining titanium's lightweight strength and corrosion resistance.

But this pen isn't just about looking good.

Its clip-activated mechanism lets you extend or retract the writing tip with a simple press of the pocket clip. No bulky bolt-action hardware, no complicated controls—just a clean, streamlined design that's easy to use.

Eight subtle grooves near the tip provide additional grip, while the compact 4.74-inch length and 0.39-inch diameter make the B1 comfortable to carry in a pocket, bag, or everyday carry organizer.

Inside, a genuine Olight O-Refill ballpoint cartridge delivers smooth, consistent writing with quick-drying, oil-based ink. The refill is replaceable, and an extra cartridge is included.

And perched at the top is a discreet integrated fidget spinner, ready for those moments when your hands need something to do while your brain catches up.

Beautifully finished, practical, and just a little entertaining.

Why We Like It

We already liked the regular B1 titanium pen.

Then OKNIFE went and gave it a finish that looks like someone captured a tiny lightning storm in the metal.

Well, that's just unfair.

The Lightning Strike pattern brings a little color and personality to an otherwise wonderfully simple design. And underneath all that blue and purple, it's still the same useful titanium pen with a clip-activated mechanism, replaceable refill, and fidget spinner.

Also, we already carry the Olight O-Refills.

Look at us accidentally planning ahead.

A Finish with Personality

The Lightning Strike treatment creates branching patterns across the titanium surface, giving the pen its distinctive blue and purple appearance.

Pattern placement and coloration may vary slightly between individual pens, making each one a little different.

Keep the Ink Flowing

The B1 Lightning Strike uses replaceable Olight O-Refill ballpoint cartridges, and we carry those, too!

The pen includes one installed refill and one spare, but you can pick up additional O-Refills to keep your favorite writing instrument in service for the long haul.
