Grind the plane to a 40-degree cross section with the rough surface on the reverse side of the grindstone, and pull it back and forth in parallel (the plane and the grindstone form 30 degrees).

2, rough grinding first, after grinding, in a place with strong light, until you see a little cutting edge on the blade, and then use a fine grinding stone mill. If you look closely, you will know that there is no sand hole in the blade.
