Hello to all. I'm at a loss I've just ordered some hiromoto AS knives but at a loss as to what to do when the times come to sharpen the knives. I've been practicing on a cheap set I currently have and doing an OK job at the minute. I've seen YouTube videos sharpening at a 45 degree turn others 90 degrees then flip the other side and procede in the same way. My question is what is the best YouTube guide for these knives or even what is the best YouTube guide altogether? More so I have a cheap double sided 800/100 whetstone what grit and or brand best compliments these knives?
