Profile

One look at a highly figured piece of Brosimum guianense and it’s easy to see why it’s called Snakewood: the dramatic specks and splotches bear a close resemblance to the skin of a snake. Such figuring can be so pronounced that it has been compared to the writing of hieroglyphics, and is sometimes called Letterwood. In addition to its colorful figure, Snakewood is also among the densest and hardest of all wood species worldwide. It is difficult to dry and has a strong tendency to form cracks.

Snakewood is so called for its characteristic snakeskin patterns. Wood is typically a reddish brown, with contrasting darker brown or black patches. Color tends to darken and homogenize with age and exposure. Snakewood originates in South Amercia.  Snakewood is difficult to work with. Cutting tools get blunt very quickly. As if this was not enough, snakewood dust is toxic. Due its limited availability we have to ask for a surcharge for Snakewood instruments. Due to strong darkening its spectacular grain will get more discreet over time.Snakewood is an excellent tone wood. Instruments made from Snakewood sound similar to those made from ebony.

Typical use

Inlay, veneer, violin bows, tool handles, and other small turned or specialty objects.
