From the front, the blade edge on the right side is about 2 millimeters higher. Basically, you sharpen both sides the same, but some people sharpen like this. It's the same concept as the Ishika (a type of plane) setup. There are no other loose spots or areas of particular concern. I'm curious about the "Tokuno" inscription on the mark. Also, the cap has a design on the bottom part, finished with a double ring. Please refrain from price negotiations, except for bulk purchases. Also, please consult in advance for bulk purchases.
