Gorgeous as always... where do you get those clear buttons from? They are really cool. Also, care to share your varnishing process? Is it just stain with poly? Tung oil with poly? The wood is beautiful.
I get the Seimitsu parts from
www.akihabarashop.com - great vendor and you can get anything that Sanwa or Seimitsu sells from him.
As for the Varnish, I do not stain. Rather than try to make a wood look like another species, I just use the species I want it to look like.

For a brown wood, I use Walnut for a purple wood I use Purple Heart, etc.
I sand the stick down to 320 grit and get everything as perfect as I can, then I clean it with Mineral Spirits. After that evaporates I apply Oil Based Polyurethane. Using a Danish Oil, Tung oil, etc is not needed as the oil based poly will bring out the grain the same way. I sand with 320 between the first 5-8 coats then I move up to 400grit between coats. I have gotten to the point where it is glass smooth on the last coat. I cant remember which coat that is though, probably like coat number 12 or higher. I lose count.
On this Walnut one, I sanded from 400grit to 600, 800, 1000, 1500 and then used rubbing compound, glaze and wax to get this:
