You can not take anything that is liquid, sharp metal, certain electronics and a wide variety of other things in your hand luggage. The laws are changing all the time so it is best to check on the TSA's website for most recent updates.
Just do away with sharp objects, liquids, gels, firearms, bulky electrics. You can pack your medications that are properly labeled, clothes is also alright, valuable like you phone, laptops, wallet, travel documents and such.
In some major airports (all in the UK) you are not allowed to take any liquids that are more than 100ml, scissors, razor blades, corkscrews or anything else sharp.
Anything else goes.
