I used a piece of ‘forest oak’ to make my extra-curricular plane wheras the timber provided for the course was ‘river oak’ both of which are casuarinas and as hard as b*ggery!
Parts of this response will be music to YOUR ears! However, there may be others who will rail and rant and claim heresy at the following. No negative correspondence will be entered in to as it works for one Japanese master craftsman and probably his master before him. Basically a new blade, like ours, or a blade with a nick, is shaped/sharpened on diamond plates from as coarse as 300# through 600# to 1000# all free hand. *
This is then followed by carborundum powder on a ground steel plate. By making a slurry with the powder AND A FEW DROPS of water, the surface to be sharpened/honed is worked on the plate with the slurry providing a progressively finer and finer grit. The slurry is a dark grey and, after being worked, it suddenly turns a dry light grey and that is the time to stop. Any further honing and/or touching up while working, is done freehand on a 6000# water stone.
* Amongst my number of ‘amazements’ during the course was the constant demonstration, to my eyes, that flatness of the sharpening medium is probably more important than the coarseness or fineness of the surface. The use of diamond plates and steel plates is a demonstration of this BUT I was ‘stunned’ (which is a step beyond amazed!) when we looked at the flatness, or lack thereof, of a batch of new, unused diamond plates. Most were not flat along either axis. Hiroshi-san marks his diamond plates to indicate which are the flattest!

Influenced by the Flettmeister, I have been acquiring Japanese toys as I can. I ran across this little number, handless on Evilbay.
I researched the chisel and the seller and decided to take the chance on it and a few of it's brethren, full well knowing that they will require fettling.
I was looking for something else, when I found a small blank of Cedrus Japonica in my stash. So this arvo I decided to turn the handle.
