I always use cable ties and usually have a pair of small scissors in an outside pocket, but there are occasional lapses. A couple of times I've had to ask the hotel staff for scissors or a knife. Once I arrived back at the Tel Aviv airport and opened my carry on to get out my house key. Not there, yikes! I carefully took everything out piece by piece with no success. Hmm, I must have inadvertently packed the key in the suitcase. I got it off the carousel, all secure with its cable ties, and no scissors in the outside pocket. It's the middle of the night so I can't wake up the woman who has my spare key, and I don't fancy sitting on the front steps waiting for hours till I can contact her. Try to find a knife or even scissors in a very security-conscious airport after 9/11 ! No one, but no one could help me airside. I finally remembered there's a florist in the terminal. Sure enough they had the necessary tool, and I quickly found the key, heaved a sigh of relief, and was home in 30 minutes.
I still use cable ties, but I'm more careful about where my house key is 😂
I've also had the ties cut off 2 or 3 times, always for security checks (though the Lord only knows why) and nothing's ever been missing.
