Frequently Asked Questions (FAQs)

1. What can I use instead of a letter opener?

If you don't have a letter opener, you can use scissors. Simply use one of the scissor blades as if it were a letter opener to open your mail.

2. Can a letter opener cut you?

Yes, a letter opener can potentially cut you. There have been incidents where people have been injured by letter openers, including an attempted assassination where a person was stabbed in the chest with a letter opener. It's important to handle letter openers with caution and keep them away from children or anyone who may misuse them.

3. Can you legally mail a knife?

5. Can you carry on a letter opener?

While letter openers are not specifically prohibited items for carry-on luggage, it is recommended to pack them in checked bags to avoid any issues or confusion during security checks.
