1916–1999 Plow production was at its peak in the 1930s, with over a million plows made. The Fiskars Kymppi plow was the most famous of these. Fiskars made many plastic products in the 1960s, including the first ergonomic plastic-handled scissors the company is perhaps best known for. The scissors were designed by Olof Bäckström, and the first pair was manufactured in 1967. There were prototypes with handles in black, red, green and orange. After an internal vote at Fiskars, the orange color was chosen. Between 1967 and 2010, over a billion units of these orange-handled scissors were sold. The design has changed slightly over time, and in addition to orange, the scissors are manufactured in other colors as well. In 1972, Fiskars was the first company in the world to start mass-production of left-handed ergonomic scissors, which can be identified by their red color. In 1977, Fiskars founded a scissors factory in the United States to provide a basis for international trade and further expansion. 2000– Fiskars Orange was officially registered as a trademark in Finland in 2003 and in the US in 2007. Fiskars acquired Iittala Group in the summer of 2007; the value of the transaction was EUR 230 million. The brands owned by Iittala were Arabia, Hackman, BodaNova, Höganäs Keramik, Rörstrand and Høyang-Polaris. With the acquisition, Fiskars became the Nordic market leader in home products. Fiskars also acquired French Leborgne, which strengthened the company's position in the kitchenware and tabletop categories, as well as the garden tools business. The acquisition of Royal Copenhagen A/S in 2013 complemented Fiskars' tableware offering with hand-painted porcelain. The company, founded by the Danish royalty in 1775, cost EUR 66 million. Royal Copenhagen was a leading brand in hand-painted porcelain in countries such as Japan. In 2015, Fiskars acquired the Waterford Wedgwood group of companies (WWRD) from a US private equity investor. The acquired brands included Waterford, Wedgwood, Royal Doulton, Royal Albert and Rogaška. The transaction was worth EUR 406 million, and it more than doubled Fiskars' net sales. The number of personnel also increased by almost 50%. In September 2015, Fiskars celebrated 100 years of being listed on the Nasdaq Helsinki Stock Exchange, along with Nokia, Wärtsilä and UPM. Fiskars recorded net sales of 1,105 million euros and an adjusted operating profit of 65.1 million euros. Cash flow from operating activities was 47.6 million euros.
