with zip ties, I took care not to tighten them all the way. By leaving a loop large enough to insert a ball point pen, for example, one can easily twist them off. With a decent small blade, you one can cut them off very easily. Of course we all arrive at our away from home destinations with no blades while thieves en route can have them.

If you are serious about knowinh how secure the TSA paddled locks are, get one, and get some pliers of various sizes. You will likely be surprised at how small an ordinary a tool can be and still effective at removing these locks.

Still, useless locks go well with all the other useless "security" we buy.
