Cocobolo is a tropical hardwood of the tree Dalbergia retusa from Central America. Only the heartwood is used: this is typically orange or reddish-brown in color, often with a figuring of darker irregular traces weaving through the wood. 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. This oil lends a strong, unmistakable floral odor even to well seasoned wood and occasionally stains the hands with prolonged exposure. Standing 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 of some varnishes, particularly oil based finishes.
Cocobolo working it
Care must be used when cutting Cocobolo, as the wood's oils can induce allergic reactions if inhaled or exposed to unprotected skin and eyes. A dust collection system, coupled with the use of personal protective equipment such as respirators, is highly recommended when machining this wood.

Poison ivy grows throughout much of North America, including the Canadian Maritime provinces, Quebec, Ontario, Manitoba, and all U.S. states east of the Rockies, as well as in the mountainous areas of Mexico up to around 1,500 m (4,900 ft) (caquistle or caxuistle is the Nahuatl term), and is normally found in wooded areas, especially along edge areas. It also grows in exposed rocky areas and in open fields and disturbed areas. It can grow as a forest understory plant, although it is only somewhat shade tolerant.[1] The plant is extremely common in suburban and exurban areas of New England, the Mid-Atlantic, and southeastern United States. Similar species, poison oak, and Toxicodendron rydbergii are found in western North America. Poison ivy rarely grows at altitudes above 1,500 m (4,900 ft), although the altitude limit varies in different locations.[1] The plants can grow as a shrub up to about 1.2 metres (3.9 ft) tall, as a groundcover 10–25 cm (3.9–9.8 in) high, or as a climbing vine on various supports. Older vines on substantial supports send out lateral branches that may at first be mistaken for tree limbs
