Can a good Person explain to me what does polishing do? or meaning of it?
Does it changes thickness of the edge?
or just makes shiny bevel?
My opinion doesn't matter how you guys call darn edge gets sharper as you go all-way (1k,2k,5k,10k, so on)until the end depends where you stop.

Here is what is being said Sham in numbers

Lets say the edge starts .at .75 microns you sharpen in the 1-4k range to .48 the last bit of finishing takes the edge to the max sharpness of .47
between the 4k level and whatever level if you go too...

Hone or paste past this mystery blade's max level of .47 then you would overhone and the edge fails at least that is what I am saying... in very simple form

Since there are many experienced members here, I have a question. Does the grind of the blade effect the impact of the shave in the context of sharpness? The reason I ask is that I feel like the full hollow is the easiest grind to use and hone, but I feel like the wedges really do better than one pass than the full hollow. I am sure its probably the honing, but I use a 12K on each and finish CrOx paste. They all easily pass the HHT and shave test, but I was just wandering if the grind effecting the feel of the edge is related to this topic.

I think so Trey, look back at posts 11-14

I kind of wish we had a scanning electron microscope at our disposal and an SRP research facility to end our speculations. Obviously the Verhoeven paper does not address the perceived comfort of an edge which I care about as much if not more so than "sharpness" or "keenness".

Honestly I love speculating about this stuff and theorizing as much as the next guy, but it can also get frustrating for me; like chasing your own tail.

I love the fact that the Verhoeven paper is there for us. I'm bummed that it leaves off where we need it or something like it to pick up. Perceived comfort based on various edges, abrasives used and subjective opinions in actual shaving. That's why I think for our specific purposes, the Verhoeven paper is only partially conclusive to what interests us.

Glen i agree with you on this 100%.
Basically you are saying you can get from razor certain sharpness after that edge just melts (ss blades) or just small chips forms (mostly 16k will do it). or bends over honing.
This is correct.

But there is some issues in here .
factor one
maker
steel
hardening how has been done. Example
some blade will never take a good edge LOVELY pakistany blades. etc.

Yes exactly each razor has a max level period....

This has pretty much been proved to be around the .48 -.38 micron level by way of the papers the Mr.Parker has linked and most of us have read...

Verhoeven also looked at steel hardness and edge thickness and found a correlation there, though it wasn't huge. But he only looked at I think 58-64hrc steel not the cast iron that the pakistanis use.
