The transportation regulations regarding weapons and sharp objects can vary depending on the country, airline, and specific circumstances. However, in general, machetes are considered dangerous weapons and are typically prohibited from being carried in carry-on luggage.

If you need to transport a machete, it is recommended to place it in your checked luggage rather than your carry-on bag. However, it's essential to verify the rules and regulations of your specific airline and destination country to ensure compliance with their guidelines. Some countries may have strict restrictions or even complete bans on carrying certain weapons or sharp objects.

To be certain, I advise contacting your airline or checking their website for specific information on their baggage policies and prohibited items. Additionally, you can also consult the customs and transportation authorities of your destination country to understand their regulations regarding the importation of weapons or sharp tools.
