Never base a decision on the advice of those who don't have to deal with the consequences.
My Gesshin Ginga 240mm grind was beautiful out of the box. Not overly sharp but it still slices very well because of that very nice thin grind. It's probably time to take it to my stones for a quick touch-up since it has been my go-to knife that sees daily use. Even last night it was used for dinner prep and finished up by cleanly slicing through a large watermelon like it was soft butter.
