Magnification under a Loupe
Here's a little post about what I see on a bevel under magnification in my loupe.
220 Grit: (rarely used) Flat bevel sides meeting at a rough edge. Scratches deep, and clearly visible. When turned the blade looks bluish steel colored, rough, and not highly reflective.
1000 Grit. Scratches easily visible, and look white under bright light. Toothy edge When the blade is turned in the light only the deepest scratches are visible and the bevel looks lightly polished and reflective.
4000 Grit: Scratches white and easily visible, and have a tight, close pattern. Fine edge When turned in the light the bevel reflects a bright polish then looks darker.
8000 Grit: Scratches are harder to see and look bright white. When turned the bevel reflects a "rainbow" polish then metallic black.
12000 Grit: (only a little experience) Scratch pattern doesn't show up well, seen only very close and at just the right angle. Invisible edge. When turned slightly the bevel turns deepest mirror black.
Natural Water stones ie coticle:(little experience) Scratch pattern can be hard to visualize but can be seen at the correct angle. Scratch pattern can be somewhat "chaotic" compared to synthetic stones and vary in size between stones. When turned the blade will look hazy and can be anything from satin, matte finish; to bright, mirror type.
