In summary, if you're wondering whether or not you can bring scissors in your carry-on, the answer is yes, as long as the blades are less than 4 inches in length. However, if the blades are longer or the scissors are deemed a security threat, they must be packed in your checked baggage.
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.

Is toothpaste considered a liquid by the TSA? Yes, toothpaste must adhere to the 3-1-1 rule for liquids and gels. Toothpaste can be brought through TSA security in your carry-on as long as it is 3.4 ounces (100 milliliters) or less and placed in a 1-quart bag.
Safety Razors: Because the razor blades are so easy to remove, safety razors are not permitted in your carry-on luggage with the blade. They're fine to pack in your carry-on without the blade. The blades must be stored in your checked luggage. The same applies for straight razors.
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).
Toothpaste is considered a liquid by the TSA (Transport Security Agency), even though it's technically a paste. In fact, all pastes, gels, waxes, and lotions are also classified as liquids. And even today, these substances are still restricted by the 3-1-1 rule in hand luggage due to safety threats.
But when you think about it, it's actually a pretty inconsiderate thing to do. By filing your nails, you're sending a cloud of your dead skin cells into the air to circulate around the cabin to be inhaled by your fellow passengers.
Stick deodorant is fine in any size. Well, almost any size… Powders and crystals are good to go as well. Spray, Gel, Liquid, Cream, Pastes, and Roll-On deodorants need to be in containers no larger than 3.4 ounces and placed in a clear quart-sized baggie.
You can pack tweezers in hand or checked baggage without any packing restrictions. But TSA doesn't allow packing sharp objects in hand baggage because some of them could be used as potential weapons. So some special types of tweezers might be prohibited if they have sharp, pointy ends.
In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container (3), all containers must be placed inside one clear quart-size plastic bag (1) and each passenger is only allowed one plastic bag (1).
