Handmade Strings Since 1919 from Vienna, Austria

In 1919 violin maker Dr. Franz Thomastik and civil engineering specialist Otto Infeld founded the company, invented the steel string and caused a revolution in the music world. Suddenly the conventional gut string was challenged by a new string with the highest quality of tone, precision and reliability. It was received enthusiastically by virtuosi across the world.

The string makes the music. The diversity and beauty of the musical timbre depend upon, on the one hand, the type of material used for the core and on the other hand, the material spun around the core. For a perfect sound, Thomastik-Infeld has consistently chosen steel and nylon as the string core material for bowed and plucked instruments.

The highest standards are guaranteed by ongoing research in Thomstik-Infeld's own research lab engaging a team of highly specialized technicians. However, tone perfection is achieved primarily by the delicate touch of fingers and the highly qualified staff in the workshops: Every string at Thomastik-Infeld is wound and checked by hand.
