No, unless you intend to transport your briefcase as checked luggage, which is the only time the TSA may want to open your luggage outside of your presence. If you plan to bring your briefcase as a carry-on, they may ask you to unlock it to look inside, but you won’t have to worry about them destroying your built-in combination lock. Is “full-grain” leather worth investing in? If you’re looking to keep your briefcase around for a long time, yes. Full-grain leather is the most water-resistant kind of leather, and it also develops an aesthetically pleasing “patina,” the glossy sheen that appears when leather is properly used and aged. Lower-quality leather briefcases will do the job, but don’t expect to be giving them to your grandkids 40 years down the line.
