No if you crush it you change the structure,
The size of the cutting particles are only part of the story, how they sit, what they sit in, and how they release, if they release all has a part in the movie "True Grit"
Even using a Diamond plate to release slurry changes things..

This is all true for Synthetic hones also, but they are screened for for uniform grit size... and a uniform Matrix to hold them and release them..

Just forget Naturals for a second and look at Synthetics.. take every 1k or every 8k and try and compare them, even having all the same grit "Size" they all perform different now toss in the unknowns of Mother Nature and the variables multiply exponentially..

Grit schmitt how does it feel on the steel, and how does it feel on the face...


Perfect example:

Shapton 1k
Shapton Pro 1k
Naniwa SS 1k
Naniwa Chosera 1k
King 1k

These all are 1k but they are very different, even the scratch patterns and depths are different... This is why I hate seeing numbers on naturals not even grit rated synthetics cut the same


And after all that add in what Dave I think was eluding to also, what about after the grit starts to break down, if it breaks down, does it hinder or help..
