Cold Steel Pocket Shark Permanent Marker & Defense Pen

As the saying goes, "the pen is mightier than the sword." Indeed, Cold Steel makes some mighty strong swords, but this little pen makes for some clever competition. It's the biggest, baddest, permanent marker around!

Superficially, it shares many features common to most markers, but appearances can be deceptive. For starters, it's made from the glass-reinforced plastic, Grivory, and features walls that are 4 times thicker than similar markers. This means it's built for impact and, in a self-defense emergency it can become an efficient Yawara stick for driving off an attacker. Plus, the screw-top cap will stay in place and won't pop off like a regular marker's cap would when you strike a percussion blow, or when obtaining joint locks or submission holds.

It's easy to carry too. Just clip it to a shirt or coat pocket, or carry in your purse, pack or brief case. Don't spend another day without one!

Customer Reviews

Well-designed except for the clip
David C. on Nov 11, 2022

Which pen works really well for it’s intended use, and is built like a tank. The only problem I have with it is that the clip tends to break off easily. When the clip does break off though, it creates an outcropping on the cap which is effective for raking. I’ve used them in Kubaton self-defense classes, both as a student and an instructor.

Works great!

Very thin point. Works great as a pen. I did not niced bleeding through paper. It is not as permanent as Sharpie.
