The design of the TSA locks is light and simplified, and not heavily engineered.

That feature accompanies the idea of light luggage, in dealing with the realities of the " creative " airline rules and regulations today regarding the movable target of weight allowances.

I do have a Rimowa Übersee Bahnkoffer, or overseas train/steamer trunk, which has been replaced by the newer version known as the Columbus. I bought it used, and with the generous assistance of Rimowa customer service, I was able to restore it. This case features three heavy hasp-type locks, an inside shelf, hand rubber handles at each end. When empty, the case weighs in at a mere 19 Kilos ( 2.2 x 19 = 41.8 pounds ).

This case can be better secured with a stronger set of locks, but anyone who really wants to using a crowbar or bolt cutter could break right in. I also don't think I will be flying with it anytime in this life due to the weight. Times have changed - Fly light, and take whatever precautions you can to be safe and secure your luggage.
