Porcelain toilet is the same thing and it has more of a flat area to work with

As long as there are no bumps or anything sticking up it might work. One bump sticking up could chip the edge. Those DE hones are dead smooth, mine is orange glass

Use your fingers to feel of it ! I know some have disagreed with using a finger earlier , but it works. Tongue would be a bad idea in this case even after washing it

The only reason I disagree with the finger is you can feel grits as small as 5 microns. Which is actually really fine. BUT when we're talking about finishing stones, we're talking about stones that (should have) grit measuring 2 microns or less. For reference:

Also check out this video from Dr Matt:



I guarantee you could pet and lick those problem coticules all day and never once notice the difference between them and one that works better/easier. But it made all the difference in the world at the edge and how to utilize the hone effectively.

Gee, it's such a novel idea to use a coticule after an 8k...

My Shapton says 0.92 microns and my finger can feel them as well if it were on some woman's leg !!!!!!!!!!

I never thought it would take 66 posts to explain what a PHIG is.

Well, the point was that Dr Matt found a method that worked with his coticules that doesn't work with everyone's coticule because of minute differences that you're not going to feel with your finger, but could see under a 900x microscope. Kinda circles back around to your comment earlier about stones that feel glassy and smooth, but still chew up an edge.

Edit: That also doesn't mean that different materials will not have a different tactile feel. My Norton 8K doesn't feel like my Dragon's Tongue, which doesn't feel like my Lynn Melynnllyn or my Black Welsh slate, and none of those feel like my PHIG. The point is, if a few stray grits of something closer to a Norton 4K fell onto one of those stones (or was sticking up from them) you wouldn't feel that, and that is what would chew up your edge.

One thing I have noticed on most if not all pictures of hones and stone is that they are always wet. On this site and ebay. The stone needs to be dry and so do your fingers.
