Leathering is what I call it and idk the correct term. But after sharpening a blade you drag it along a leather strap on both sides and miraculously it becomes razor sharp. The seemingly subtle motion on a softer surface makes a night and day difference of the sharpness of the edge. WHY?!? Edit: the it

This is called stropping. It works because it straightens the edge of the blade. Sharpening makes the edge thinner, but a thin edge that isn’t straight still won’t cut as well. Stropping the blade ensures that the edge will be both thin and straight, maximizing the blade’s cutting ability.
