Grit Ratings ?

“Estimated” Grit Ratings

Actually i wanted to support a certain “type” of grit estimation for this site. We all know that when it comes to natural stones that each individual stone for sure has differences within its natural matrix. It can contain other mineral inclusions, other types of materials and within the matrix the particles sizes can vary.

But its always good to offer a certain grit rating for interested people. This means that the findings here on the RAZORLOVESTONES page are my personal findings and i created my personal “Grit Matrix”. So please don’t nail me on any of the ratings i wrote down here. Each person might identify a same stone, even having the same stone in his hand to another grit then the one before.

All these ratings are estimations, but for sure feel free to comment or write an email to me to discuss or correct a statement i did in one of my posts.

Here is my personal grit matrix for the site:
extreme coarse – 100grit – 500grit (> 0,1 – 0,5K)
coarse – 500grit – 1000grit (> 0,5K – 1K)
medium coarse – 1000grit – 2000grit (>1K – 2K)
medium –  2000grit – 6000grit (>2K – 6K)
medium fine – 6000grit – 8000 grit (>6K – 8K)
fine – 8000grit – 10000grit  (> 8K – 10K)

The finer grits work just with an above (>) or under (<) estimation
very fine – under 12000grit (<12K)
ultra fine  – above 12000grit (> 12K)

Ultra fine might reach something above 15K and up, there are several stones (especially the french stones) around dealing with very very fine edges. Sometimes oil or glycerin is used on certain stones to reach that fineness and to buffer the contact between the stone and the material.

Also some Jnats might reach that goal, also when in my point of view the “Slurry Breakdown”  in relation to “60K Jnats” theory has been ruled out from
