I sometimes wonder if the growing but small NA variety in selection leads to a sort of circle jerk. I'm really thankful for vendors and makers who have expanded outside Japan, but what percentage of quality production are we seeing?
My Doi yanagi's are fast and pleasant to sharpen, give a good looking contrast, and balance bite and precision... Compared to others that I over polished or just didn't get. But I've used maybe 5-6 brands of single bevel knife ever so that's for what its worth.
