    Default Shapton GS Before Jnat

    I've been following all this talk about Shaptons/Sigmas & am very curious about getting some to use before my Oozuku. Wouldn't happen until after I get a new job, but I'm doing research in advance.

    I'm thinking 500 (for serious bevel work if needed), 1,4,8, Oozuku (it's a fast cutter & I want to give the slurry a chance to break down--if I keep it really light & work it I actually get an almost mirror finish off of broken down slurry before I even go to water). I was poking around So's site & noticed he recommends 1,2,6 before the Jnat. Any ideas why? Allowing for longer slurry breakdown maybe?

    you can use the Oozuko after 8k, but you will need to use nagura and tomonagura for best results.
    You can get on your ozuko from 6k synthetic but you will have to spend more time on it.

    That's what I'm usually coming off of. I've been using a scope lately (doing lots of experimenting) & actually do think that more refined is better before the Jnat! Straight from the Norton was an interesting experiment, but I think there's a lot to be said for using a good prepolisher 1st. Under the scope the difference between the 8k scratches & even slurry sandblast is jawdropping--probably 30k easily on slurry, judging by the scratch size. There's no reason to wear out my tomonagura polishing that out!

    Coticule or finer before the Jnat it is!

    To quote from one of So's emails, "This is a very minimalist approach. I would argue more stones are needed haha"

    he probably isn't even talking about razors.
    I am very positive there is no finisher that can take on a 6k edge, in a reasonable amount of time.

    The email was definitely to a razor stone customer I was testing a stone for but as So said it is a "very minimalist approach" not the ideal approach.

    Well, when I am in the mood I go from one of those "narutakis" I have, which I estimate to be around the 6K mark (perhaps slightly higher) straight to the nakayama asagi. It does take longer than if I inserted an intermediate grit hone in there, but it is not prohibitively long, at least in my experience.

    Mind you, since I got that Ozuku suita working again I rarely jump from the 6 to the Asagi any more.

    I also often go from the Shapt 16 to the asagi too. Works fine. There's many ways to skin a cat, as my grandmother used to say!

    Agree. I normally go from the Shapton 16k GS to the J nats. As previously stated, the sharper, the better.
    We have assumed control !
