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
Spokeshave way in which such a tool was used; the categorization is based entirely on the appearance of the tool. Spokeshaves can be made from flat-bottom, concave, or convex soles, depending on the type of job to be performed. Spokeshaves can include one or more sharpened notches along which the wooden shaft is pulled in order to shave it down to the proper diameter. Historically, spokeshave blades were made of metal, whilst the body and handles were wood. An early design consisted of a metal blade with a pair of tangs to which the wooden handles were attached, as with a
