Using Japanese sharpening stones of various grits and considerable prices, Junskitchen set out to try and make an edge of a $1 kitchen knife. The results are impressive-but how long will they last?
[1,000 and 6,000] grits would be enough for a normal household knife. I used grits 1,000, 2,000, 5,000, 8,000, and 12,000 in this video. The higher the number, the finer the sanding and the sharper the knife will be.
