Tona was founded in 1892, originally as an iron foundry. The production range then gradually developed over the following years, through the production of agricultural machinery and engineering products, and in the 1950s to the production of craftsman's tools. During this period, its own forge was also built, a decisive step towards stabilising the production programme.
Gradually, the production of all types of wrenches was introduced - open-end, closed-end, socket, socket, screw and wrenches. Tona became part of the IAR division, focused on supplying tools for car repair shops and industry, and also of the global EXPERT project, within the framework of which the offer is being transformed and modernised under the new brand - TONA EXPERT.
