Grab a Red Oxx Cable Lock and you’ll never need to remember a combination to your luggage padlock again. The end isn’t crimped, but has the look that it is. Instead it just twists off like a normal screw. Security through obscurity. You can also use them as a key chain or miscellaneous tie wrap to secure little belongings. These cables are available at quite a few online retailers, but for the price Red Oxx has them at, it doesn’t hurt to grab a few.
