Thread: Okudo Karasu

Thank you very much, so much to learn for a such a small stone. But I think it won't be the first Jnat. That way I love straight razors, when you say I know everything about sharpening, Coticule thuringians, manmade, here is another brand new experience.

I always strop on my hand between changing stones or nagura, that minimizes the false edge problem.
Sometimes I end with swiping my palm over the stone getting some fine slurry on it, let it dry and then strop on it.

I honed 2 razors, one Mogal, hard steel, one Heljestrand MK 42, both 12k Naniwa shave ready,
they both pass HHT from the hone, before stropping, then I make 30 passes on Ozuku,very light ,just water, they both seem to sucked onto the stone, they both pass the HHT,before stropping,and even better after stropping. I will let you know the shaving impression tomorrow.
So , for now I will try it without slurry , just as a regular finishing natural. I will do more passes, less passes, the stone seem to release very light slurry when honing.

Sounds good! I also will post my experiences with my Okudo Karasu as I begin to use it...

Then it's self slurrying and probably works fine with water only.
Just had the last of the coffee but soon will have another pot on, so no hurry!

The idea that using a diamond plate to raise a light slurry will quickly wear out a stone, well I know that over time it would, yes. I have flattened literally 100s of stones with the Atoma 400 plate, and I am a stronger man for it, and I am using as fresh a plate as I have, bearing down with my full body weight under running water. It is such a chore that I have to take breaks and even walk away from it for a few minutes. It takes so much time and effort to just lap out a 0.05mm divot, I cannot see myself actually wearing out a 20mm thick hard awasedo razor hone in a lifetime of normal slurry raising. Softer stones, yes, they do wear out faster and under an Atoma you can get that divot out in maybe 2/3rds the time, but really hard stones like razor users have, it would be a slow process to deminish a stone.

Even the 140 grit Atoma can be a bit slow on certain stones. I find 40 -80 grit SiC powder on glass speeds things up considerably until the diamond plates can come into play.

Thank you all for your suggestions, I try it after a very fast coticule, a deep rock, I raise slurry on coticule and dilute about half way. After I finish on Okudo , 100 laps, is a small stone, the edge is improving considerably over the coticule on water. The shaving is absolutely fantastic, I don't even need 2 passes. For now, this is my favorite finisher, beter than my Hohenzollern. I will post more of my experience, as i will try it with slurry.
