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

Like the others said it’s stropping.
Sharpening with Steele can only make it so fine. Leather makes it like a razor blade
I use a straight razor to shave and I have to strop every few times. Rough edge on the leather 10 times and smooth edge 40 times.
I can feel the difference on a freshly stropped blade
Edit: microscopically leather can fine tune the edges to sharpen the thinnest of a metal surface without breaking it. Thats what happens with a harder compound. Think of it as trying to sharpen a stick with a saw vs a knife
