Here's a vid I stumbled upon while re-watching some of J-Bro's vids. It's shot by a customer who bought a knife(s) from Aritsugu and was getting a basic sharpening lesson from one of their employee's.
The lesson is much more basic than what J-Bro has shown in his vid's, and there are some slight differences in technique. Yes, this vid leaves out many elements of sharpening, especially for single bevel knives, but for a basic lesson for a first timer I think it's a good place to start someone.
One quesiton I have - the young gentleman says that when sharpening the back-side, the mud MUST be washed off of the stone. Why?
enjoy!
