. But TSA recently confiscated a mini Swiss-Army knife from my mom in Providence, a treasured souvenir she had in her purse for 20 years (thus my SASE).
I had a treasured mini Swiss-Army knife confiscated once too. It had been through security dozens of time before. Funny thing was I had a full blown SA knife in my carry on camera bag that I usually transfer to checked luggage but forgot and it went through. It's really hit or miss. Like your mom, I really liked that tiny knife.
