Cold Steel - Pocket Shark Self Defense Pen 91SPBK

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, 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!
