During World War I, Söderberg & Haak delivered tools to the military, including axes. A special metals unit was established during the war with the greater importance of copper, brass, tin, lead and aluminium in the company’s product range. By the end of the war, Sweden was suffering from a severe shortage of foodstuffs. As a result, in 1917, Söderberg & Haak acquired a cow and housed it in the stable for the work horses. Employees were offered free milk and children also received buns from the company.
