    Hmmm... I have a couple hard vintage coticules, one that's especially hard, that I will have to play around with more. Thanks for the good tips/ideas/info here fellas!

    Do harder cotis usually cut faster or do they just normally provide a finer edge?
    It depends on the stone in question plus slurry no slurry. In general the harder stones cut slower without slurry, but give a keener edge. With slurry it depends on the stone and the slurry stone in question and the properties of each along with the concentration of them in the slurry.

    Thank you all for your input.

    I will try a little longer with the slurry stone, for a few minutes. If not successful I will get a super fine (1200) diamond stone as suggested.

    My daily shaver is sharp but other razors I have need major sharpening, thus creating slurry is a must. Regarding the use of softer stones, I have done that, but since I spent the pennies on a very special piece of coticule, I do want to try out its properties with slurry as well

    That makes sense. For some reason the I thought a harder stone would be faster cutter. Now that I think about it hard Arks don't cut like soft arks do with pocket knives. Now it seems like a goofy question.

    Very Hard Coti's that do not slurry easily do not make for good all around hones

    ie: Stones that finish very well might not lend themselves to lower end work without the use of softer Rubbers

    I think many of use would view that as a good thing

    Thank you all

    I tried light rubbing for about 2-3 minutes, until I started to see a hazy slurry, very little water and more rubbing got my some slurry. I don't recon you can set bevels with it. For that you would need a soft stone, but is good for the latter part. The edge is amazing.

    I use a Translucent Arky pocket hone as a rubber on most all my finishers, It is flat and much harder and does not drop any grit.
    I am glad your got a great Coticule!

    Just avoid the credit card sharpeners from DMT...The backing is very thin and it bends easily...making th enickel plating crack...moreso th enickel plating is very thin and they ware off incredibly fast.
