Pen Knife with Concealed 2.13-Inch Blade – Functional Ink Pen with Hidden Stainless Steel Blade, Twist-Apart Design, 5.38-Inch Overall Length, Pen Cap Safety, Available in Black, Silver, Gold, Red, Camo

A Pen That Does More Than Write

There are situations where having a small blade available is useful — opening packages, cutting cord, everyday utility tasks. And there are people who’d rather not carry something that looks like a tool or draws questions.

The Pen Knife is exactly what the name suggests: a working pen with a blade inside. It writes. It clips to a pocket or notebook. And if you need a cutting edge, you pull it apart.

Who This Pen Knife Is For

People who want a discreet utility blade that doesn’t look out of place in an office, a briefcase, or a shirt pocket. It’s practical for everyday cutting tasks — opening mail, trimming loose threads, scoring tape on a box.

It also appeals to people who simply prefer carrying fewer things. Instead of a pen and a separate knife, this combines both functions into one item that weighs less than an ounce. If you already carry a pen daily, this replaces it with something more versatile without adding anything to your pockets.

Simple Design, Practical Function

The pen separates into two halves with a twist-and-pull motion. One half contains the ink cartridge and writes normally. The other half houses the 2.13-inch blade. When assembled, the pen looks and functions like any standard ballpoint — there’s nothing externally indicating it contains a blade.

The overall length of 5.38 inches is within normal pen dimensions, so it fits standard pen clips, pen holders, and shirt pockets without drawing attention. The pen cap covers the blade end when assembled, serving as both a writing cap and a safety measure. At 0.06 lbs, it adds essentially nothing to what you’re already carrying. Available in five finishes — Black, Silver, Gold, Red, and Camo — so you can match it to your preferences or professional environment.

Practical Details

Overall length is 5.38 inches. Blade length is 2.13 inches. Weight is 0.06 lbs. Includes a functional ink cartridge. Pen cap serves as the blade safety when assembled. Available in Black, Silver, Gold, Red, and Camo. Check local laws regarding concealed blade carry — regulations vary by jurisdiction and some locations restrict blades regardless of how they’re carried. This is a utility item, but legal requirements differ by area.

A practical everyday tool that earns its place in your pocket by doing two jobs instead of one. Be Prepared and Be Safe.
