Research it:
https://www.wood-database.com/cocobolo/#:~:text=Allergies%2FToxicity%3A%20Notoriously%20allergenic.,%2C%20and%20asthma-like%20symptoms.
Cocobolo is becoming rare and the slash and burn politics in Brazil are reducing habitat every year. It's my personal belief that Brazilian and Cocobolo are blood commodities and I don't want anything to do with using mass quantities of it. I don't have any Brazilian bridge blanks.
I'm not going to participate in that mentality were the guitar collector is in the philosophical space of - Oh I know the wood is rare, but I just want to get mine before it's too rare. - Cypress is easier on the planet and grows faster and in more places.
From the page:
Odor: Cocobolo has a distinct spice-like scent when being worked, which some find unpleasant: though it has been used in at least one women’s perfume.
Allergies/Toxicity: Notoriously allergenic. Reported as a sensitizer; can cause skin, eye, and respiratory irritation, as well as nausea, pink-eye, and asthma-like symptoms. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Cocobolo is in limited supply, and is also in relatively high demand, (for ornamental purposes), and is likely to be quite expensive. Prices should compare similarly to other rosewoods in the Dalbergia genus.
Sustainability: Cocobolo is listed on CITES appendix II under the genus-wide restriction on all Dalbergia species—which also includes finished products made of the wood. It is also listed on the IUCN Red List as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.
Common Uses: Fine furniture, musical instruments, turnings, and other small specialty objects.
Comments: One of today’s most prized lumbers for its outstanding color and figure; yet also one of the most infamous for its difficulty in gluing, and its tendency to cause allergic reactions in woodworkers.
Also, there are a few misleading reports of Cocobolo’s Janka hardness being only about 1,100 lbf, and it’s modulus of elasticity at only about 1,100,000 lbf/in2: which is almost certainly either a typo or a different wood than what is commonly called Cocobolo (Dalbergia retusa). Reports indicate that Cocobolo is stronger and denser than Brazilian Rosewood, and that is the basis for the strength values (bending strength and modulus of elasticity) that are quoted at the top of this page.
Specific gravity is used to predict the hardness of wood with a fair degree of accuracy, and given its incredibly high density, (it sinks in water: see video below), Cocobolo’s hardness (and other strength properties) is most likely several times higher than the 1,100 lbf which is sometimes reported.
