I'm planning a month-long trip and am wondering which of these items are okay to be kept in a carry-on bag. Could you help classify these items as "allowed" or "not allowed" by the TSA? Toothbrush, Cologne, Beard Shaver, Alcohol, and Bottle Opener.

Here is what's allowed and what's not allowed in your carry-on luggage:
- Allowed: Toothbrush, Cologne (3.4 Ounces), Beard Shaver
- Not allowed: Alcohol, Bottle Opener
