The article It’s too big of a jump! showed that the scratches produced by a Shapton Pro 320 grit hone and a Shapton Glass 16k hone do not display a fifty-fold difference in depth or width, although the nominal grit size in those two hones differs by a factor of fifty. To further demonstrate this phenomenon, this article compares the swarf (the metal removed to form the scratches) from those two hones and the Shapton Glass 2k, which falls halfway between them in grit.
The first set of images show the swarf collected from a 320 grit Shapton after honing a carbon steel straight razor. In these images the bright objects are abraded steel, the majority of which have the familiar shape of turnings from machining waste, albeit at much smaller scale. The darker particles are broken or dislodged abrasive.
The swarf from the 2k Shapton glass stone ranges in size from approximately 2 microns to approximately 1/10 micron.
The swarf from the 16k Shapton glass stone ranges in size from approximately 1 micron down to less than 1/10 micron.
