This is exactly what it looks like on the outside — a regular pen. Pull it apart and there’s a 2.13-inch blade inside. It writes, it clips into a pocket or notebook, and nobody gives it a second glance. Available in five colors: Black, Silver, Gold, Red, and Camo.
The pen knife concept is simple: it looks like a pen, functions as a pen, and conceals a small blade that’s only accessible when you deliberately pull the two halves apart. At 5.38 inches overall — a normal pen length — it sits in a shirt pocket, a bag pen slot, or a notebook ring without standing out. The ink cartridge is functional, which means you can actually use this as a pen without blowing the cover.
The blade is 2.13 inches, which is on the shorter end of pocket knife blades. It’s not a utility tool for heavy tasks, but for the situations where a compact blade is useful — opening packages, cutting cord, having a backup option in your pocket — it works. The pen cap covers the pen tip end; the blade is accessed from the other end by pulling the sections apart.
This is a good fit for someone who wants a small blade that travels discreetly — in an office, at a desk, in a travel bag. Because it looks like a pen, it doesn’t carry the same visual weight as a folding knife clipped to a pocket. Some people prefer that. It’s also a reasonable backup option for someone who already carries a primary tool but wants something extra that won’t be noticed.
It’s worth being realistic about what a 2.13-inch blade is suited for. It’s a compact utility and personal defense option, not a heavy-use cutting tool. If you need something for regular outdoor tasks or work, a purpose-built folding knife would serve better. If you want something small, unobtrusive, and always in your pocket, this covers that well.

The design is straightforward. The pen looks and functions like any ballpoint — clip it into a pocket, use it to sign something, leave it on a desk. To access the blade, you pull the two pen sections apart. There’s no thumb stud, no button, no one-hand deployment. It’s a deliberate two-handed action, which also means it’s not going to open unexpectedly.
The ink cartridge is a standard refillable type, so when it runs dry you’re not stuck with a decoration — you can replace the cartridge and keep using it. At 0.06 lbs, it’s light enough that you genuinely won’t notice it in a pocket.

Overall length: 5.38 inches. Blade length: 2.13 inches. Weight: 0.06 lbs. Safety: pen cap covers pen end; blade accessed by pulling sections apart. Includes functional ink cartridge. Available in Black, Silver, Gold, Red, and Camo. Check your local laws regarding blade length and concealed carry regulations before purchasing — rules vary by state and municipality.
If discreet carry matters to you and you want something that doubles as an actual pen, this is a well-thought-out design. Pick the color that works for you and keep it where you keep your pens.
Yes. The ink cartridge is functional, and the pen writes like a standard ballpoint. This isn’t just for looks — you can actually use it as a pen on a daily basis. When the ink runs out, the cartridge can be replaced with a standard refill, so you’re not stuck with a non-functional item.
Blade length laws vary significantly by state, city, and county. Many jurisdictions allow blades up to 2.5 or 3 inches in public carry, which means a 2.13-inch blade often falls within legal limits — but not everywhere. Some areas also have specific rules about disguised or concealed blades. Before carrying this regularly, it’s worth looking up your local regulations. We can’t provide legal advice, but your state legislature’s website or a local attorney can clarify what applies to your area.
The pen has two sections that pull apart. The blade is housed in one end; the pen tip and ink cartridge are in the other. To deploy the blade, you grip both sections and pull them apart — it’s a deliberate two-handed motion. There’s no thumb stud or spring mechanism. To close it, you push the two sections back together. The pen cap goes over the pen-tip end during normal carry.
No — this cannot be carried in an airplane cabin. TSA prohibits all knives and bladed items in carry-on bags, regardless of length or how they’re disguised. You could pack it in checked luggage following standard rules for bladed items in checked bags, but it cannot go through security in a carry-on. If you travel frequently and want something you can take on a plane, a personal alarm or certain pepper sprays (checked luggage only, with restrictions) would be better options.
