More about Palissandre Palissander wood is one of the most frequently used species in the history of woodworking which is why it is so often found on furniture but also in knife handles. Its use can be traced back to the end of the 16th century until the 1970's when overexploitation led to its quasi disappearance from the market. Because it was so endangered it was listed on Annex 1 of C.I.T.E.S* in June 1992 and its trade is now forbidden except for stocks which predate the convention. For the renovation of 17th and 18th centuries-style furniture it has been replaced by a Brazilian rosewood species : dalbergia spruceana. *Convention on international trade of endangered species of wild flora and fauna a.k.a CITES or Washington Convention is an international agreement between States. Its purpose is to make sure that international trade of animals and plants does not endanger the survival of their species.
