What Finish for a Ebony Spokeshave
I chose to go with a combination of buffing, shellac, and wax. This is a picture of the finishing products used.
Now to the blade. The blade comes dull. The bevel and the bottom do not totally meet at the cutting edge as can be seen by this highly advanced drawing:
This is what is wanted:
To achieve this you must grind away the excess to make the sharp point. I did this freehanding it on my grinder. This is a drawing of the most desirable situation. Usually on a conventional blade I would do this step with my honing guide and coarse diamond stone, but the spokeshave's threaded posts prevented me from doing any serious grinding on the bevel.
As you can see, this makes the non-beveled side become like a hollow ground blade on a conventional blade like this:
The advantages of the hollow grind are that it reduces the amount of steel that needs to be taken away to sharpen, which makes the process quicker. After doing this to the bottom of the shave blade, I was able to achieve a sharp edge.
The blade I bought from The Japan Woodworker came with a photocopy of David Charlesworth's article on making a spokeshave. Unfortunately they didn't actually photocopy the entire thing, so I had to go to the library and rent the book the entire article is in. I also used this article by John Gunterman. Both were very helpful.
This tool will prove to be very useful in upcoming projects.

A good solution indeed. Old wooden shaves often have a similar hollow forged into the "flat" face of the blade.
