The TSA rules for razor blades in 2026 are very specific: disposable razors and cartridge razors (like Gillette or Venus) are allowed in both carry-on and checked luggage because the blades are permanently encased in plastic. However, safety razors and straight razors are treated differently. The handles are permitted in carry-on bags, but the individual sharp blades must be removed and packed in checked luggage. TSA officers are not authorized to remove blades for you, and if they find an encased blade in a safety razor during a carry-on scan, the entire item may be confiscated or the blade discarded. Electric razors are fully permitted in both carry-on and checked bags without restriction. If you are traveling with just a carry-on and prefer a safety razor, your best bet is to buy blades at your destination or ship them ahead to your hotel to avoid security delays.
