LIGNUM VITAE. The hardest wood in the world
Lignum vitae tree |
Lignum Vitae is regarded by most to be both the heaviest and hardest wood in the world. Its durability in submerged or ground-contact applications is also exceptional. Lignum Vitae has been used for propeller shaft bearings on ships, and its natural oils provide self-lubrication that gives the wood excellent wear resistance.

Unfortunately, Lignum Vitae has been exploited to the brink of extinction, and is now an endangered species.
