same cautions, plus, apply in asia. anything weaponish, including most fixed blades, are forbidden even in checked bags that only transit hongkong and japan. i had a nice filipino country-side made, fixed 3-4” blade pulled from my checked bag upon entering manila airport before checkin. i was going via hongkong to usa. the security guys demanded that i abandon it, and clearly were jonesing over who would pocket it. i pulled my bags back, went outside and gave it to a friendly porter. those security guys were sure sad my second time through.

living or traveling throughout asia, the mideast, carribbean, africa and europe for 3 decades+ i deep pocket carry a swiss army knife that includes a few tools, especially a cork screw. never have a problem, probably because the euros and japanese appreciate wine, and it’s a neutral country knife.
