@mariorossiexcite the green liquid is most probably antifreeze. many japanese knife grinders use it as it doesn't rust the blades. very unhealthy practice...
Thanks for the clip. I was suprised to see the wheel had not been dressed back to round. I always thought the Japanese were into accuracy & precision, not just get the job done.
A good observation. Wheels that are supposed to be flat are dressed several times a day. This particular wheel is 'undressed' to more easily allow a grind on a recurved shape like a scythe. A flat stone this width would not follow the tighter radius of a recurved blade like a scythe, Note that these wheels are used for the initial coarse grind and are ~ 100 grit and not the final polishing wheels or the hand sharpening to follow..
What's the green liquid in the tank?
