Other names by which the tree is known include babanus and grenadilla, which appear as loanwords in various local English dialects. The genus Dalbergia yields other famous timbers such as Brazilian rosewood ( Dalbergia nigra), Dalbergia cearensis and cocobolo ( Dalbergia retusa).African blackwood is no longer regarded as ebony, a name now reserved for a limited number of timbers yielded by the genus Diospyros these are more of a matte appearance and are more brittle.The trees are being harvested at an unsustainable rate, partly because of illegal smuggling of the wood into Kenya, but also because the tree takes upwards of 60 years to mature. Henckels sell knives with blackwood handles due to the wood's moisture repellent qualities.ĭue to overuse, the mpingo tree is severely threatened in Kenya and is needing attention in Tanzania and Mozambique. ![]() The German knife companies Wüsthof, Böker and J. A story states that it has even been used as ballast in trading ships and that some enterprising Northumbrian pipe makers used old discarded blackwood ballast to great effect. Furniture makers from ancient Egypt on have valued this timber. The Deering Banjo Company uses blackwood ("grenadilla") to construct the tone ring in its John Hartford-model banjo because it weighs less than brass or bronze tone rings, and that the wood "plays in" (improves in tone) with use. Those properties are particularly valued when used in woodwind instruments, principally clarinets, oboes, transverse flutes, piccolos, recorders, Highland pipes, and Northumbrian pipes. The timber is used mainly because of its machinability, density, dimensional stability, and moisture repellence. Good quality "A" grade African blackwood commands high prices on the commercial timber market. It is generally cut into small billets or logs with its sharply demarcated bright yellow-white sapwood left on to assist in the slow drying so as to prevent cracks developing. The dense, lustrous wood ranges in colour from reddish to pure black. The fruit is a pod 3–7 cm long, containing one to two seeds. The flowers are white and produced in dense clusters. The leaves are deciduous in the dry season, alternate, 6–22 cm long, pinnately compound, with 6–9 alternately arranged leaflets. It is a small tree, reaching 4–15 m tall, with grey bark and spiny shoots. Populations and genomic resources for genetic biodiversity maintenance in parts of its native range are threatened by overharvesting due to poor or absent conservation planning and by the species' low germination rates. The tree is an important timber species in its native areas it is used in the manufacture of musical instruments and fine furniture. & Perr.) Kuntzeĭalbergia melanoxylon ( African blackwood, grenadilla, or mpingo) in french Granadille d'Afrique is a flowering plant in the family Fabaceae, native to seasonally dry regions of Africa from Senegal east to Eritrea and south to the north-eastern parts of South Africa. In contrast, our exclusive Nano-Glass files can accomplish all rough work, shaping and finishing in one easy step! Our Nano-Glass technology is measured in nanometers (nm) which is approximately 80,000 times thinner than a human hair. ![]() Common glass files also require additional filing from buffers and papers creating two, three and sometimes a four-step process. Unlike common glass nail files which wear quickly and can cause micro-fiber tears weakening the nail, our Nano-Glass files can last up to one year! Our files produce a precision finish without ever compromising nail strength. These trees grow an average height of 150ft with a trunk diameter of 4-5 ft. It is a large tree native to central America and its name is used to describe several tree species and the wood derived from them. They often have an interlocked or wavy grain pattern. Wood textures range from medium to coarse with a slight shine. Zebra Wood is characterized by its yellow, golden heartwood with dark brown striped figures reminiscent of the majestic zebra.
