Terry, Right track! Use some black aniline dye stain ( assuming they are ebony) and follow with Watco or other real danish oil finish. I have good results applying with a "Q" tip. Let it dry a bit and follow with another coat. Let dry o'nite and repeat. Do this as many times as you think appropriate. When you have it where you like you can either leave it or knock down the sheen with 4/0 wool if you so desire.
