The company, Fishing weights Ktistakis Ioannis, was founded in 1947 in Thessaloniki, by Ioannis Ktistakis focusing on the processing and casting of lead. More specifically, by making the weights for the fishermen’s nets of the season, who until then had made the weights they needed for their nets alone, cutting off leaded pipes. This was the first time in Greece to establish the professional weights for nets.
