Wood the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred. This is particularly the case in the choice of hickory for handles and spokes. Here not only strength, but toughness and resilience are important. The results of a series of tests on hickory by the U.S. Forest Service show that: The effect of rate of growth on the qualities of chestnut wood is summarized by the
Field hockey stick picture further. In the early 1990s there were an astonishing number and variety of hockey sticks on offer compared with what had been available ten years earlier. By 1992, hockey stick reinforcement was a big issue and composites had been accepted into an (extended) FIH experimental trial period (there was a great deal of concern about the power generated by these new reinforcements and the safety of players). There were also hockey sticks with metal handles and inserted plywood heads (made by the American company Eastons, better known for making baseball bats), as well as the wide range of one
