I've had good experiences with natural snakewood. It's harder and more brittle than ironwood, but it takes a nice finish. It is pretty much impermeable to water and fairly scratch-resistant. I don't consider it a hard-use material, though. Partly because of the brittleness, and partly because I don't want the high-gloss finish to get scuffed up.
All of the material I get has been air-dried for a fairly long time at the yard, and I like to keep it round my shop a bit before I use it. This makes it less likely to crack unexpectedly. When sanding, use sharp abrasives, snakewood heats up and scorches very quickly. I finish it by hand, sanding to 8000 grit finishing paper, and maybe add a light coat of oil.

P.S. I hear that the non-figured material is considerably tougher than the figured stuff. It's a nice-looking wood in it's own right, too.
