Santos Rosewood

Santos Rosewood carries a name that can mislead: it isn't a true rosewood from the Dalbergia family, but a wood all its own, Myroxylon balsamum, native to the tropical forests stretching from Central America down to Peru and Brazil. It earned the "rosewood" name for its color and some related acoustic traits, but it's a harder, denser wood with a character all its own. The moment the blade cuts into it, you know you're dealing with something out of the ordinary: a spicy, almost balsamic scent that follows every pass. That's no accident, trees of the Myroxylon genus produce Balsam of Peru, a historic ingredient in luxury perfumery.
The color ranges from golden brown to deep burgundy red, with darker streaks and an interlocked grain that develops a ribbon figure under raking light, elegant and understated. Over time it tends to deepen toward richer, darker tones. Janka hardness sits between 2,200 and 2,400 lbf, placing it among the hardest woods in the tropical hardwood world, stable, wear-resistant, practically immune to weathering. It isn't CITES-listed and has no availability issues, a rarity among exotic woods of this caliber.
Its tight density makes it technically suited even to fine-line engraving, the wood doesn't give and the mark stays precise. The dark color does call for care in choosing the subject, though: on designs with good contrast and well-defined shapes the result is excellent, while very fine details risk getting lost in the dark background of the surface.
