It's a recurring rock star nightmare: You're backstage on the opening night of your first world tour—the crowd's roaring, begging you to come back and play one more solo, but you're out of guitar picks. What to do? Well, first, you'll probably wake up. But if not, you can just turn to your trusty DIY pick maker. This guitarist gadget takes unwanted plastic materials, like expired credit cards or old IDs, and punches them into custom plectrums. Keep it at home or in the studio, or carry it in a gig bag to ensure a new pick is never far from reach. Made in China.
