COCOBOLO - (Dalbergia retusa) Cocobolo is a tropical hardwood from Central America. The heartwood is typically orange or reddish-brown in color, often with a figuring of darker irregular traces weaving through the wood. By contrast, the sapwood (not often used) is a creamy yellow, with a sharp boundary with the heartwood. The heartwood is known to change color after being cut, lending to its appeal.
Cocobolo is oily in look and feel, and stands up well to repeated handling and exposure to water: a common use is in gun grips and knife handles. It is very hard, fine textured and dense, but is easily machined, although due to the abundance of natural oils, the wood tends to clog abrasives and fine-toothed saw blades, like other very hard, very dense tropical woods. Due to its density and hardness, even a large block of the cut wood will produce a clear musical tone if struck. Cocobolo can be polished to a lustrous, glassy finish. The high natural oil content of the wood makes it difficult to achieve a strong glue joint, and can inhibit the curing process of some varnishes, particularly oil based finishes.
Cocobolo is from Central America. Cocobolo from Mexico is more straight grained and darker in color, Cocobolo from Nicaragua is more colorful and more figured in grain pattern.
