These are some tested airplane carry-on and TSA compliant weapons. Results may vary and depend on many factors and conditions.
Anything technically classified as a “weapon” is restricted as carry-on for essentially all commercial flights, TSA (American airspace) and globally alike.
But a tool doesn’t have to be classified as such to have the utility of a weapon, literally anything can be. The only thing matters is its effectiveness and practicality – also in this case, permissiveness.
I currently equip the following non-weapon “weapons” in various everyday carry kits and loadouts, all of which are transported carry-on when I fly.
Hot Tamale Coin Purse | [BUY]
Made by Mean Gene, this holds a dozen or so coins and holsters itself to belts. Equally it’s also a leather sap, an extremely powerful one. Although I haven’t had any issues with security, I’d be extra cautious about bringing this through highly sensitive locales.
BSS V3 Torch | [BUY]
Made by Black Scout Survival, this may not be the best tactical flashlight available, but it may just be the most functional in a close quarters combat capacity. The removable strike bezel is fiercely proficient and the light itself is blindingly bright at 1000+ lumens.
Operator Pen | [BUY]
Made by Tuff-Writer, this is the gold standard of tactical pens. Writes as well as it attacks and defends as a exceedingly fast and naturally deploying force multiplier. The most widely permissive and casually (legal) carryable non-weapon “weapon” available.
It should be noted that what constitutes a weapon or otherwise restricted item is ultimately at the discretion of the security agent or law enforcement officer. Practice common sense with caution.
