Edge Pro sharpening stone (0.5 inch), grain 400

This sharpening stone is intended for us in the Edge Pro sharpening system. Because the sharpening stone is only half an inch wide (1.3cm) it is very suitable for sharpening a knife with a curved blade. The curve of the blade is much easier to follow on a narrow stone than on a wide one.

The grit size can not be directly compared to the grit sizes of Japanese water stones. Use therefore the table given here.
