2 HISTORY The tool production in Hulin began in 1934. The firm was founded by Mr. Studeník who named the new company " First Moravian factory" for saws and tools". At first the company started producing hand saws, circular saw blades and was gradually enriching the production programme with cutters for wood cutting and other tools for wood working. In the 1960th the production assortment enriched with TCT circular saw blades, gang saw blades, planner knives, machine knives, metal cutting tools and saw bodies. In the years 1948-1992 the firm was a state-owned enterprise. In 1992 the firm was...
