Tool Logic was founded in January 1995 with the introduction of the Credit Card Companion. This ultra slim (1/8"- 4mm) credit card size tool kit was designed to be an alternative to the traditional Swiss Army-type folding knife. The combination of functional tools, high quality engineering and ease of carry, rapidly made the Credit Card Companion a success. It also established the value of credit card format multi-tools in a world where compact size and light weight are at a premium.
All of these credit card tool kits are manufactured to Tool Logic's exact specifications by one of the world's leading makers of specialty cutlery.
