TSA-proof knife
After decades of using a Utili-key as my choice of a small knife to pass through airport security, I lost it in the woods. I replaced it with Victorinox SwissCard. This tool is a mini-Swiss Army knife flattened into a plastic holder the size of credit card but thicker. It has a tiny (1.5 inch) sharp blade, scissors, tweezers, a pen, toothpick, and a pin. You can carry it in your wallet or bag. Goes through security. There is a knock-off version which remarkably adds a magnifier, a light, and four screwdriver heads in the same size card for half the price at $9 — but you’ll need to sharpen the flimsy blade. — KK
