Development since 1890

In 1890, Lars Håkansson worked for one of the leading steel mills in Sweden as a Hardening Master, which enabled him to develop a patent for a new hardening method.

After his retirement, his son Gustav took over responsibility for the Hardening Department – becoming himself a well known authority in his field. In 1944 he joined his brother, Bror Håkansson, the founder of Håkansson Industrier AB, and a new division was founded, Håkanssons Sågblad, that became the very first non-American manufacturer to specialize in  hardened band saw blades with a flexible back.

In 1946 Gustav pioneered in the heat-treatment of band saw blades using high-frequency technology (induction hardening).

He was also active in the development of milling machines for band saw blades.
