Every week, the TSA blogs about items (mostly weapons) that agents have confiscated at airports around the country, and the agency posts some of the crazier items on its Instagram page. Check out the 5 items that we at Team TPG think are the most ridiculous items that were confiscated this month. Once again, we’re happy to see that the TSA has prevented these items from being smuggled on board aircraft with hundreds of other passengers!1. Concealed KnifeWe’ve seen plenty of passengers try to bring knives on board aircraft in carry-on bags, but this is another level of sneaky. One passenger flying from San Francisco (SFO) mistakenly thought they could trick the TSA by hiding a knife in a bottle of pills.Knives of any kind aren’t allowed to travel with you on board the aircraft.2. “Designer” Knife SetWhile these pink knives look the part, they’re knives nonetheless and can’t travel in carry-on bags. These knives can fly if they’re securely stowed in checked luggage.No matter how pretty they are, knives have to be packed in checked luggage.3. Ninja GearWhile this set of ninja weapons looks like it could be in an action movie, they can’t fly in the cabin with you. Remember to pack these in your checked bag if you want to travel with them.This full set of ninja gear can’t fly in a carry-on.4. Cane SwordThe cane/sword combo weapon is definitely one of the more unique things we’ve seen people try to get by the TSA. Luckily, this weapon was no match for the X-ray machines at LGA and was confiscated before it was able to get on board an airplane.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

It looks like someone made a DIY trailer hitch/hand grenade and then decided it was a good idea to pack it in a carry-on bag. Even if the grenade is not active, it absolutely can’t fly, as there’s no way to be certain it’s inert without calling a team of professionals to examine it. The next time you have the urge to bring a grenade with you, just leave it at home.This crazy grenade trailer hitch was confiscated at San Luis Obispo County Regional Airport in California.What’s the strangest item you’ve seen at a TSA checkpoint?
