Thanked: 4Extremely Stupid sharp...
a) I've been thinking that after my 16k shapton arrives there are a few more steps that might be added.
b) I noticed woodcraft has a grade A granite surface plate for 30$.
I love woodcraft.
c) I know my local lee valley has sheets of 3M .5 Micron chromium paper.
d) And I noticed that japanesewoodworker has 3M .3 micron silicon oxide paper.
When I combine these thoughts I find myself wondering whether it might be possible to hone a razor up to the point of completely unusable
Woo hoo!!!!
The 3M papers have a wonderfully even distribution of material so one can hone rather than strop.
e) I'm also wondering whether a honing jig might provide that impossibly light even touch that I probably won't learn for another 1000 razors.
I'm looking for feedback, additions or embellishments. My razors are already more than sharp enough off the chinese 12k and .5 chromium paper, then .25 diamond strop, newsprint and leather but I'm curious how sharp is sharp.
Thanks,
Bob

I thought you wanted to reduce the dermis removal?

Thanked: 4Lol, this is purely in the pursuit of science rather than better shaving.

Thanked: 735I use Bueller diamond lapping film taped on a sheet of glass to hone my razors. It works great.
You can get similar stuff here:
http://rshughes.com/products/051111_61574.html?
I have 9um, 6um, 3um, 1um, 0.5um, & 0.1um grades. (I don't bother with the 0.1um actually)
I use a honing motion (i.e.- edge first), and have no problems
The diamond is bonded/fused into the polymer film, so it lasts a long time. I am not familiar with the cromium paper, but I'm sure it will do the trick very nicely as well, it just may not last as long. But it is probably cheaper?
Sometimes I play with putting a single sheet of paper underneath the lapping film, as this seems to give it some cushion and smoothness. If I put 5 sheets of paper under there, it is too much and it doesn't polish the bevel evenly.
Get some and try it out!

This is an admirable goal, but don't forget that you will be sacrificing edge longevity.

I think he is referring to the time between honing and rehoning... the sharper you go the sooner you will have to go back to the hone.
and yes if you go too sharp your edge can collapse while shaving, and you will end up with a dull razor very fast.
The holy grail is a razor that is super sharp, but feels smooth, and doesn't break down in a week... I have such a razor, but I'm not sharing.

In this day and age of "Scientific Superiority", I'm kind of surprised that there's not a company out there that can bring a blade to absolute "Perfect Sharpness", without the need for honing or stroping.....The blade would be made from High-Speed Tool Steel, Carbide, or some other alloy that would be super-hard......and retain it's edge indefinitely.....
and, speaking of the edge.......It would be inspected under an electron microscope to make absolutely SURE that it was undeniably PERFECT !
(or am I just wishing for too much) ?.......

Thanked: 44Yeah you will definately be sacrificing honing longevity. I shave with .25 micron edges but I only sell .5 unless .25 is requested because i find that people mess them up otherwise. This is a recent change. They also have .1 micron diamond paste that you can use but when you get to a point you no longer have a comfortable shave either.

Rather than unusable, you're more likely to overhone and end up with a wired edge. I like your thinking, but I'd go sparingly on the different polishing levels since you are thinking of using so many.
