In my last Youtube vid I showed one of the perks of using a translucent SAK: simply apply pro-grade glow-in-the-dark tape to the tweezers and toothpick (or an even greater area if you are willing to remove and replace the scales) to make your own keyring "glowfob". In this video I show a similar trick: how by using a photo-copier in HQ mode (600dpi, or better) you can make your own club card (laser bar code for store checkout scanners).
