Hey man! That's not fair!
You're supposed to be rubbing one rock against another and making grunting noises in front of an open fire.
But thanks for all the pictures, anyway.
The round white "crumpet-stone" is the one I want. Really fine grained. That one is the keeper.
Water slurry. No. Don't. The slurry is a slop of smashed abrasive particles which plugs up the cutting stone's surface.
Like oil, the water is no more than the vehicle to flush the swarf off the stone face to keep it cutting cleanly and not plugging up.
On a water stone, after a grind, you can fake a finer grit by letting the swarf build up. I never do.
I want to know that my 1500 grit stone is cutting cleanly at 3 microns average particle size.
Now to action = which way will you go?
Move the stone over the knife edge OR, move the knife edge over the stone?
Which will give you a more consistent bevel angle, stroke after stroke?
What did Mungo Martin do? Hint: One way works far better than the other.
