I'm sorry - my bad........
A "faux" finish means a false finish, sometimes used by Japanese manufacturers on guns, to make sub-standard wood look like spectacular Black Walnut.
It's usually done artistically by the application of a base color coat, then laying in a woodgrain pattern in a darker contrasting color - similar to what's seen in high-grade presentation wood.
Sometimes, it's done via a hydrographic dipping process (think: camo dip, but in woodgrain)
The results are then covered/finished with a clear epoxy (spray).
I found this out the hard way - by sanding such a stock for refinishing, breaking through to the blond/white junkwood beneath.
