Cool Tools has a post on Uncle Bill’s Tweezers. These are excellent tweezers that hook onto your key ring and don’t get taken away at airports (so far). I’ve carried a pair of these for nearly fifteen years, ever since our youngest started crawling. It is my default small gift for new fathers. As soon as their child starts crawling, they’ll need to pick splinters out of baby knees. Works for adults, too.
I get mine from the display beside the cash register at Barron Park Plumbing Supply. They are a fine plumbing store and right next door to the original site of Shockley Semiconductor.
