Some Tactical Pens may be pretty neat gadgets, like the Colt Defender Tactical Pen with its carbide glass breaker and LED light, but unfortunately they can sometimes be too “tactical” looking for their own good. TSA is well aware of them for example, so the chances of them taking it away are high.
Fortunately there’s always options. One of them is the Zebra F-701. 100% pure ordinary non-tactical pen. While it lacks the carbide glass breaker, LED and somewhat of a kubotan shape common to tactical pens, its still pretty solid given its stainless steel construction.
Tough, cheap at around $5 and theres no place where it cant go along with you.
