Teak is a hard wood with an open pore structure, similar to mahogany. It is seldom used for guitars because it is somewhat difficult to work, and very hard on tools.
This beautiful instrument was built from a teak cutting board that I got for free from Home Depot for review. 32" Eden neck, active electronics. Teak is hard enough for a simple oiled finish. This one was built with a minimum of tools, mostly by hand, to show that it can be done and how.

Here's a freebie nut spacing rule I made some time ago. Just print it out on a piece of paper, and fold it over on the centerline. Don't worry about the printer scaling, it doesn't matter. To use the rule for a guitar, mark the two E strings on the nut and slide the rule until the marks line up with 4 between them. Et cetera.
