CTA Manufacturing started in 1978 with a few specialty tools and a lot of great ideas. After spending over 25 years setting up worldwide distribution for the biggest names in the business, the founders of CTA decided to take some of their own ideas to market. Originally named "Classic American Tools", the company expanded from manufacturing about 20 Specialty Tools to well over 1000 tools under the CTA name today. Factories are located worldwide, manufacturing Specialty Tools to meet the demands of today’s technicians.
