"I need to learn how to 'work the mud' now to get exactly what I'm looking for on each knife Ken or Mark do you have any videos on that?"
It's a different stone - A Hakka Tomae - which is a finer stone but also quite muddy. This would be an example of working the mud."me 2...I have a vintage Aoto and it is most definitely the best stone that I have. Just need a good 6-8k stone at the moment."
A good followup stone for the Aoto is a Meara stone in this range. A good bit harder but extremely versatile.
If anyone needs more detail and instruction, just contact me.
