Finally finished this up. Added more red ink to the handle, gave it more layers of clear shellac, and put something of an edge on it. Not as sharp as I typically do; unlike most of my other work, this is more of an art piece, and I'd rather not have accidental cuts happen while it's on display.
A closeup showing that the handle is indeed an integral socket:
And showing the full length of the handle. That's a plug of pecan wood on the end, sealled with black shellac.
I gave it to my brother in appreciation for his help through the years. He seemed to really like it!
