Overview

Professional Summary

Cocobolo (Dalbergia retusa) is one of the world's most beautiful and coveted turning woods. Its kaleidoscopic color palette — ranging from orange, red, and yellow to deep brown with irregular black streaks — is virtually unmatched. With a Janka hardness of 2,960 lbf, exceptional stability, and natural oils that create a self-polishing surface, it's the holy grail of pen turners and knife makers.

In Plain English

Cocobolo might be the most colorful wood in the world — vivid oranges, reds, yellows, and dark streaks all in one piece. It's hard, dense, and polishes to an incredible natural shine. Beloved by pen turners and knife makers, but it's expensive and increasingly hard to find legally.

Sources, Conditions & Safety

No documented references are attached to this profile yet. Its recorded values should not be treated as source-verified.

Wood dust & sensitivity

Species-specific safety information has not been documented here. Absence of a warning does not mean the wood is safe or non-allergenic.

Use dust extraction and appropriate protective equipment; consult occupational-safety guidance. This is not medical advice or food-contact approval.

Durability & Performance

Decay ResistanceVery Durable
Outdoor SuitabilityExcellent

Workability

Overall RatingModerate
MachiningMachines well despite hardness. Natural oils create self-lubricating cuts. Polishes to a mirror finish.
Blunting EffectModerate
GluingDifficult — natural oils require thorough surface preparation with solvent wipe before gluing
FinishingNatural oils can interfere with film finishes. Best left natural with oil/wax or buffed to a high natural polish.

Sourcing NotesCITES Appendix II and IUCN Vulnerable. Heavily restricted international trade. Always verify documentation.

CITES Appendix II regulated. Natural oils cause severe allergic reactions in many workers — one of the most sensitizing woods. Always use proper PPE. Oils can prevent glue adhesion.
