Yes, contrary to popular belief, nail clippers are allowed on planes. As are tweezers, small scissors and even small knives (except in the US for the latter). Therefore, there is no good reason not to travel light; you can bring everything you need.
Firearms, ammunition, and fireworks are prohibited, as are all knives and safety razors (including pocket knives and Swiss Army knives). Straight razors and replacement blades for straight razors are also not allowed. Most tools also cannot be packed in carry-on luggage, as they have the potential to cause harm.
Here's TSA's answer on the official TSA Twitter channel: Tweezers are good to go in carry-on bags. Safe travels! Tweezers are allowed in carry-on and checked bags, but sharp objects should be securely wrapped to prevent injury.
Checked Bags: YesIf packed in carry-on, they must be less than 4 inches from the pivot point. Any sharp objects in checked bags should be sheathed or securely wrapped to prevent injury to baggage handlers and inspectors.
Looking for a mid-flight manicure? Nail clippers, nail-trimming scissors and cuticle cutters are totally fine in your carry-on bag. But if the blades are over 6 cm in length, they will need to be packed inside your checked luggage (this same rule applies to small tools such as calipers and drill bits).
Sharp objectsYou can bring tweezers into the cabin, and scissors with rounded ends and blades less than 6cm long. Razor blades are only allowed in the cabin if they're set in plastic. Knives with a blade not exceeding 6cm can be taken on board. Other sharp objects are not allowed in the cabin.
The TSA rules allow for lipstick to be considered a solid, not a liquid or gel, which means that you do not have to take it out of your carry-on during the security check.

Yes, toothpaste is considered a liquid when flying and must be within the 3.4oz (100ml) limit for liquids in order to bring it in your carry-on bag. Any amount larger than that must be checked with your luggage.

However, when packed in carry-on bags, makeup in a liquid, lotion, gel, paste or creamy form, must be in containers that are 3.4 ounces or less. You can take as many travel-sized liquids as you can comfortably fit into one quart-sized, zip-top bag. One liquids bag is allowed per passenger in carry-on bags.
Disposable razors, replacement blades, and electric razors can go in either your carry-on or checked baggage; if you have a safety or straight razor, you can pack it in your carry-on — but you must remove the blades first and pack them in one of your checked bags.
