Remember that most teak that you see does not have a real fine finish layer on it. You apply teak oil to the deck to keep it from drying out and splitting, but a smooth, shiny surface would kind of defeat the purpose of the non-skid deck. I don't know what an 800 grit "hard" oil finish would look like on teak. I have read that plantation teak like the stuff that is grown commmercially in Central America does not have the same oil content as old growth stuff. Much of that stuff is left unfinished or, at best, hit with some kind of wood "sealer."I will keep that in mind. I was very pleasantly surprised at how nice teak was to work with. All my life I thought of teak as decking and rub rails. I have never seen a teak burl. That's worth looking into. For kitchen knives, you'd be hard pressed to find a better handle material than teak if looks are not paramount. A burl might be a real winner.
