Pen Knife – Disguised 2.13-Inch Blade, 5 Colors

Most people never think twice about a pen clipped to a pocket or sitting on a desk. That’s exactly the point. The Pen Knife keeps a 2.13-inch blade hidden inside a working pen, so you have a personal defense tool within reach without announcing it to anyone around you.

Who This Knife Is For

This is a practical option for someone who wants a low-profile backup blade they can carry daily without drawing attention. It fits professionals who work late, travelers who want something light and discreet in a bag, or anyone who prefers their everyday carry to look like ordinary office gear. If you’re already carrying a pen, this replaces it with something that does a second job when it counts.

Legal Notes

Disguised knives like the Pen Knife are legal to own and carry in many U.S. states, but some states, cities, and venues restrict or prohibit them. Laws vary and change. Check your state and local regulations before you buy or carry this knife. When in doubt, know the rules for wherever you plan to take it.

Pen Knife: Frequently Asked Questions

Does the Pen Knife actually write?

Yes. An ink cartridge is included and the pen functions as a real writing instrument. It holds up to casual inspection as an ordinary pen, which is the whole point of the disguised design. Keep in mind the cartridge is standard and can be replaced like any pen refill when it runs out.

How does the Pen Knife blade deploy?

Remove the pen cap to access the blade. The cap serves as the safety, keeping the blade secured during carry. When the cap is on, the blade stays put. When it’s off, the blade is accessible. It’s a simple system — straightforward to use once you understand how it works.

What is the Pen Knife blade length and overall size?

The blade measures 2.13 inches and the overall length of the pen is 5.38 inches. That puts it in line with a normal pen in terms of how it looks and feels in your hand or pocket. The size is intentional — compact enough to carry discreetly, not built for heavy utility cutting.

Is the Pen Knife legal to carry in my state?

Disguised knives face different rules than standard folding knives, and those rules vary significantly by state, city, and even venue. Some places prohibit them outright. Before you carry the Pen Knife anywhere, check the laws where you live and anywhere you plan to travel with it. This is your responsibility as the carrier.
