⚖️ Why This Rule Exists: Cabin Security, Blade Restrictions & Sterile Area Integrity

Sharp blades, pointed metal tools, strike implements, and sporting equipment (bats, clubs, martial arts tools) are strictly prohibited from the passenger aircraft cabin to prevent potential weapons or coercion in the sterile area. They must be safely sheathed and packed in checked luggage.

Decision Threshold: Blades and strike tools must be transported in checked luggage only.

How to Avoid It: Check all backpack pockets and keychains before leaving home to avoid surrender at the checkpoint.

How to Pack Brass Knuckles for a Flight

Screening and criminal law are different exams. TSA will let brass knuckles ride in checked baggage with a shrug about state law — and Canada fails you at the border regardless: they’re prohibited weapons under the Criminal Code, confiscated on sight. Inside the US, several states ban possession outright; “the screener let it fly” is no defense at the destination. Collectors: ship them legally, uninsured-by-screening.
