Cocobolo is a tropical hardwood of Central American trees [1] belonging to the genus Dalbergia . Only the heartwood of cocobolo is used; it is usually orange or reddish-brown, often with darker irregular traces weaving through the wood. The heartwood changes color after being cut and can be polished to a lustrous, glassy finish. Being quite dense and sometimes having a specific gravity of over 1.0, it will sink in water. The sapwood (not often used) is a creamy yellow with a sharp boundary between it and the heartwood.
Cocobolo is yielded by two to four closely related species of the genus Dalbergia , of which the best known is Dalbergia retusa , a fair-sized tree, reported to reach 75–80 ft (23–24 m) in height and 3 ft (0.9 m) in diameter; [1] it probably is the species contributing most of the wood in the trade.[ citation needed ] Because of the high value of the timber, the trees yielding it have been heavily exploited, so they have become rare outside of national parks, reserves, and plantations. Only small amounts of this prized wood reach the world market, and it is expensive.
Cocobolo heartwood contains oil, which lends a strong, unmistakable floral odor even to well seasoned wood and occasionally stains the hands with prolonged exposure. The high natural oil content of the wood makes it difficult to achieve a strong glue joint, as in applying veneers or guitar fingerboards, and can inhibit the curing of some varnishes, particularly oil-based finishes. Acetone may be used to remove surface oils before gluing. [1] The oil can induce allergic reactions if inhaled or exposed to unprotected skin and eyes. This is due to the presence of allergenic chemicals such as S-4'-hydroxy-4-methoxy dalbergione, R-4-methoxy dalbergione, and other quinones and phenols. [2] A dust collection system, coupled with the use of personal protective equipment such as respirators, is highly recommended when machining this wood.
Because it stands up well to repeated handling and exposure to water, a common use is for gun grips and knife handles, and duck calls. It is very hard, fine textured, and dense, yet easily machined. The abundance of natural oils, however, causes the wood to clog abrasives and fine-toothed saw blades, like other hard, dense tropical woods. Besides its use on guns and knives, cocobolo is favored for fine inlay work on custom, high-end cue sticks, police batons, pens, brush backs, bowls, pipes, jewelry boxes, desktops and other expensive specialty items.
Due to its density and hardness, even a large block of the cut wood will produce a clear musical tone if struck. Renowned for its "warm, rich palette", [3] cocobolo is used to make musical instruments, such as oboes, flutes and clarinets--especially boutique, custom barrel joints for B-flat clarinets. Other woodwind instruments, such as bagpipes (as well as the chanters of bagpipes' more basic relatives, duck and goose calls), have been successfully made using cocobolo instead of the orchestral and Celtic instruments' customary mpingo, or African blackwood, known in the trade as grenadilla. Additionally, cocobolo has been used to make fingerboards, as well as entire necks and bodies of guitars and bass guitars, having been employed as a substitute for Brazilian Rosewood since that fellow Dalbergia member was CITES listed in 1992. Additionally, cocobolo is used to an extent in building drums[ citation needed ].
Logs, sawn wood, and veneer sheets from the Guatemalan populations of Cocobolo (Dalbergia retusa), have been listed under CITES Appendix III [ clarification needed ] since 2008. In 2011, Panama extended that listing to include all products except seeds and pollen and finished products packaged and ready for retail trade.
As of January 2, 2017, Cocobolo is protected as a CITES Appendix II [4] species, along with Bubinga (Guibourtia demeusei, G. pellegriniana, and G. tessmanni), other true rosewoods (Dalbergia spp.) and related species found in the Dalbergia genus, such as Tulipwood, Kingwood, and African Blackwood.
Ebony is a dense black/brown hardwood, coming from several species in the genus Diospyros, which also includes the persimmon tree. A few Diospyros species, such as macassar and mun ebony, are dense enough to sink in water. Ebony is finely textured and has a mirror finish when polished, making it valuable as an ornamental wood. It is often cited as one of the most expensive woods in the world.
Dalbergia is a large genus of small to medium-size trees, shrubs and lianas in the pea family, Fabaceae, subfamily Faboideae. It was recently assigned to the informal monophyletic Dalbergia clade : the Dalbergieae. The genus has a wide distribution, native to the tropical regions of Central and South America, Africa, Madagascar and Southern Asia.
The oboe d'amore (Italian for 'love oboe';, less commonly hautbois d'amour, is a double reed woodwind musical instrument in the oboe family. Slightly larger than the oboe, it has a less assertive and a more tranquil and serene tone, and is considered the mezzo-soprano of the oboe family, between the oboe and the cor anglais or English horn. It is a transposing instrument, sounding a minor third lower than it is notated, i.e. in A, so it can also be known as a Mezzo-Soprano Oboe. The bell is pear-shaped and the instrument uses a crook or bocal, similar to but shorter than that of the cor anglais, also known as the English horn.
Dalbergia melanoxylon 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, to southern regions of Tanzania to Mozambique and south to the north-eastern parts of South Africa. The tree is an important timber species in its native areas; it is used in the manufacture of musical instruments, sculptures vinyago in Swahili language and fine furnitures. 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.
Rosewood is any of a number of richly hued hardwoods, often brownish with darker veining, but found in other colours. It is hard, tough, strong, and dense. True rosewoods come from trees of the genus Dalbergia, but other woods are often called rosewood. Rosewood takes a high polish and is used for luxury furniture-making, flooring, musical instruments, and turnery.
Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs.
Kingwood is a classic furniture wood, almost exclusively used for inlays on very fine furniture. It was the most expensive wood in general use for furniture making in the seventeenth century, at which time it was known as princes wood. It is brownish-purple with many fine darker stripes and occasional irregular swirls. Occasionally it contains pale streaks of a similar colour to the sapwood, as in the picture.
Acacia melanoxylon, commonly known as the Australian blackwood, is an Acacia species native to south-eastern Australia. The species is also known as blackwood, hickory, mudgerabah, Tasmanian blackwood, or blackwood acacia. The tree belongs to the Plurinerves section of Acacia and is one of the most wide-ranging tree species in eastern Australia and is quite variable mostly in the size and shape of the phyllodes.

Tonewood refers to specific wood varieties used for woodwind or acoustic stringed instruments. The word implies that certain species exhibit qualities that enhance acoustic properties of the instruments, but other properties of the wood such as aesthetics and availability have always been considered in the selection of wood for musical instruments. According to Mottola's Cyclopedic Dictionary of Lutherie Terms, tonewood is:
Wood that is used to make stringed musical instruments. The term is often used to indicate wood species that are suitable for stringed musical instruments and, by exclusion, those that are not. But the list of species generally considered to be tonewoods changes constantly and has changed constantly throughout history.
