In 1852 Haktor Thorsen erected two large warehouses on one of his farms in Sunde and started trading and salting herring. This was the start of an industrial adventure that made Sunde into one of the first industrial communities in Kvinnherad.
Alvøen is one of the oldest industrial places in Norway. As early as the 1620s a gunpowder mill was built here. The place itself was well situated for industrial activity, lying only 100 m from the waterfall, which provided power for the mill, and a good harbour wherefrom the products were shipped. The success of the gun-powder mill varied in the 1600s and 1700s, but what made Alvøen best known was its paper production.
Having passed well over the bridge across to Sotra you pass an industrial plant surrounded by a budding community; the mineral mill of A/S Norwegian Talc. Some of the buildings seem to have been erected in the early part of the 20th century. They are remnants of a grand industrial plant from the former boom time in the country – the economic upswing after WWI.
As early as 1862 Svein L.Røsseland started a country store and lodging house at Ytre Tysse, and later on he became steamship agent and the first post office manager in Samnanger. However, the decisive change came when F.Mathiessen started A/S Samnanger Uldvarfabrik (woollen factory) in 1886.

The three spades in the municipal coat of arms for Modalen are sand spades. Sand quarrying has brought income and employment. As much as 70,000-80,0000 tonnes of sand and gravel left the municipality each year since the turn of the millennium, to be used as cementing sand. Why is Modalen endowed with so much sand?
