Historically, the first written reference to our file production was discovered in the registers of a Church in Konstanz, near the lake Bodensee. It mentioned the company’s founder and my ancestor, Mr. Isidor Braun, considered a master in file grinding and file teeth cutting. Our company, however, was only officially established in 1792, having moved to upper-Austria later, in the middle of 1848. Our Blu-Dan trademark, a tribute to the Blue Danube River that crosses Austria, was officially registered in 1952, and is recognized world widely as a symbol of quality and performance among professional tools. Accordingly, and after several tests from independent authorities, our trademark was awarded with the «Austrian Trademark» quality Seal.
