Do you like the center of the edge to fall directly below center of the spine or on a right handed gyuto (70/30 edge angle - left 6.5,right 15 degrees for example) would you rather allow for more right side convexity and have the edge left of center.
I have tried a little variation and I am not good enough to tell the difference. Even if the edge was 50/50 it could still be designed to the left.
Sometimes the left side of gyutos look like the are pretty oriented toward the left.
If you have any other thoughts on what grind you like as the knife goes toward the spine I would love to hear about your thoughts and I will add some of my thoughts.
