I'm an ex-boatbuilder and have used quite a bit of teak - I'm surprised more knife makers don't use it. Sam Wilson is correct - the teak needs to be wiped at least 3 times with acetone before gluing. West System G-Flex epoxy is the best for gluing because it was specially formulated for oily wood.
Once the scales are shaped and sanded to 240 grit, wet sand with the oil at 240 grit and let sit for 5 min. Wipe down and let dry for 24 hrs. Wet sand with 600 grit and oil, let sit for 5 min., wipe and let dry for 24 hrs. After that, apply as many coats as you want - at least 10 - wipe on, let sit 5 min. wipe off, let dry 24 hrs. between each coat. Before applying a new coat of oil, I like to go over the handle lightly with very fine bronze wool to remove any fines or dust which may have settled on the wet handle.
Most teak oils have a UV inhibitor so any good brand should work. I have had good results with Starbrite Premium Golden Teak Oil. Old timers swear by Dalys Seafin Teak Oil, which I haven't tried, but plan to try on my next knife.
