TEAK WOOD
Teak is a hardwood, but teak wood is softer than most domestic hardwoods and even some softwoods. Its Janka hardness rating is around 1,000, which is less than walnut, birch, ash, oak and even some species of pine and cypress. Far from being a disadvantage, teak's softness contributes to its workability. Considering that teak wood is so long lasting and attractive, it's no surprise that it's a favorite among woodworkers.
Teak heartwood is golden- to medium-brown in color, and the grain is generally straight. The surface feels slightly greasy due to the presence of natural oils. A-grade teak is generally knot and blemish free. B and C grades are used primarily by builders and craftspeople in the countries in which the trees are harvested, and they aren't exported.
