The final
polish must be done carefully.
During the final strokes, a wire burr will be formed at the edge. Keep alternating several strokes on the bevel, then several strokes on the back. When the Wire burr falls off, you have a perfectly sharp edge.
When you look at the edge under bright lighting, you won't be able to see the edge if it is sharp. If you see a glimmer of light from the edge, it isn't sharpened all the way. Simply move back to the fine stone and work the edge a little more.
