It's a shame but tennis sales are falling and manufacturing is all too similar! Maybe they should go in to Cricket? Vienna - Austrian ski producer Kneissl declared bankruptcy Tuesday, in a development that could spell the end for the first company to mass-market carving skis. The Kneissl group had amassed 23.3 million euros (31.8 million dollars) of debts, according to Austrian press agency APA. The company had hoped for a cash injection by its Saudi co-owner Mohamed al-Jaber, but the investor did not meet a deadline set by the bankruptcy judge. Founded as a carriage workshop in the mid-19th century, Kneissl became the first serial producer of alpine skis in Austria in 1919. In the late 1990s, Kneissl was the first to market carving skis, whose curved edges made turning easier and revolutionized both amateur and competitive skiing. But Kneissl's strategy of expanding and buying brands such as Raichle, Dynafit and Marker was not successful, leading to bankruptcy in 2003, followed by a series of ownership changes. Al-Jaber announced Tuesday he is ready to inject another 1.2 million euros once a strategy for the future of the brand has been worked out with the main creditors.
