Is it the Crown lamp auger bit that you want to sharpen? If so, I think that using a diamond hone on the flat angled face of the bit should work. Be careful that you do not rock the hone as you sharpen the face. Do not touch the cylindrical face nor the inside of the flute.

Bill, it is an auger bit I purchased from Woodworkers Supply. It did not come sharpened and from looking at the tip I cannot get a clear idea on how it should be sharpened.

Or is it the one with the twist like Packard? Tough to tell at the Woodworker site.

Looks obvious. What's scratched is what's sharpened. Roy Underhill uses them, and his are honed and stropped to the state of a carving tool.
I have a couple of antique tool books downstairs that might show more. After they pick up the kids, I'll take a look.

Looks like one of the diamond "credit card" files would be the easiest to work the bevels.
As MM mentioned, it seems pretty clear what to sharpen. The dotted outline indicates what appears to be bevel on the back side although the top side needs to be flattened to make smooth contact with the wood being cut. This part requires care that you make the bevel angle such that it is making contact at the toe and not the heel but not so aggressive that it digs in and jams.
