Remember that “TSA safe” means neither “guaranteed not to be confiscated by the TSA”, nor “permitted through security at airports outside the USA”.
I had a nice little Leatherman multitool, with no knife blades and “TSA approved”, which consistently got through TSA checkpoints (occasionally after a bit of explanation) but was confiscated the first time I passed through an airport security checkpoint outside the US (during a connection in Narita).
