Pernambuco comes from Brazil. It is reddish brown in color, and is a very hard wood that is readily workable. A wax varnish is used to preserve the natural reddish brown color of the wood.
Pernambuco is also used to make violin bows. The pieces of wood used to make Graf von Faber-Castell writing instruments are sawn timber. This sawn timber is unsuitable for the production of violin bows only due to its size, although the wood is of impeccable quality.
Thus, the collection makes sensible use of raw materials that can no longer be used to manufacture violin bows due to their size.
