I never expect to have to take this shaver to a 1k again. But it was overground. Also small burrs can be created on higher grit stones. Hence one reason to strop to work harden the wire edge or burr to break off. But a lot of that is dependent on the steel and stone.

I don't see the need to drop below the Rika 5k again. All I need to do is sustain.

There is plenty steel left.

Too many laps on finishing media can result in a weak edge and your edge become harsh, not great for a comfortable experience.

Yeah I'm trying to find the sweet spot. While the .25 micron was crazy sharp. It wasn't as comfortable coming off the natural with hakka tomo.

And that is the difference in honing knives and razors. It is not just about sharp, you have to hone for comfort.

Which Nano grit sprays are you stropping on?

How did you grit rate your natural stone progression?

The balsa was a .5 micron diamond paste. The .25 micron is a cbn spray on horse leather.

I used synthetics, except for the aoto (2-3k) at lower grits. the jnat that is used as a finisher is probably around 8-10k. Most of this stuff I've also used for my high end knives.

I'm always looking for more stones, and more knives. Now I'm starting to delve into razors and will probably and experiment with more razors. Usually any hobby I pick up, I go off into the deep end.

Your finisher may or may not be, 8-10k but what are you basing the estimation on?

Diamond paste is notoriously harsh, especially on balsa and when used with pressure.

You might have better luck with .50um CBN, then .25um CBN, and skip the Diamond paste, but you first have to have a finished edge.

What method are you using to establish a fully set bevel?

I base the estimation on other people's thoughts, and my own experience with synthetics. Obviously jnats have variation. But is harder and feels finer then the kitayama 8k I have.

I don't follow your last question. For bevel set, I used 1k and used both edge leading and tailing strokes parallel to the stone.

It is a nice shave already, there's always room for improvement. But I am already better then my DE razor.

Just another thought. You use .25 on horse leather but do you strop on clean leather?

I believe Eluclid means what method do you use to make sure you have a fully established bevel along the full length of the razor. IE light reflection test. Thumb pad test?

Currently not. I still would like to get a hanging strop. The horse leather is mounted on a flat surface.

There we go, always finish with clean linen and at a minimum clean leather, your fizzog will thank you for it.

I would recommend reading everything in the SRP library. This will help you iron out the difference between honing a knife and honing a razor as though similar, not the same.
As I said, the clean leather strop is an essential tool in maintaining and producing a comfortable shave. You can use denim or even better palm strop until you get one.
