Thread: 15-20k Jnat, True or False

What are the collective thoughts from SRP concerning this vendor, and his Jnats for razors? 15-20k. True or False?

I would check chef knives to go. I've seen quite a few ozuku koppas(odd shape) sell for like $100 or so. I've personally seen at least three and they were all sisters. Good finishers. I can't speak for what your looking at or the seller.

It is Chefknivestogo.
I just wasn’t sure about the forums rules for posting links.

It does say chefknifestogo. Grit size is not real as we know how that goes. But i have Jnats that can feel like a 15k plus. I think i would call them and ask for the koppas to see if they have any or when they might be coming in.

If you want to spend that much then go for it but its more than id spend for it.

I have a cktg ozuko koppa. I would guesstimate 15k plus, but it rock from the ground, and there will great variances. Also a lot depends on skill of honer.

If I was going to spend that much I’d would chat with Alex at the japanstone.com. Tested stone with matched nagura plus 30 day return

Not an expert on stones but grit range is elusive and incomplete for naturals if I understand correctly. From the little I know (from trying to find this out myself) the best way to tell is to do a scratch test and compare to scratch patterns made by stones of known quantities. I've been told to try it out and examine what it produces and figure out where it fits in a progression. I know that seems incomplete and vague, at least it did to me. In the end it isn't the grit that matters but what it does to a blade that matters.

"works quite well with razors"
Quite well is not good enough for me personally.
Not meaning to be negative but that's what jumped out at me...
On the plus side, they seem quite cheap.

Just have to comment on the scratch test Paul brought up. I agree with most stones. But with a Jnat, the Kasumi (SP) finish doesn't look like scratches. So, in this case, you can't go by that. JMO.

Thanks Jerry. As I said I'm no expert on stones. See? You learnt me something. One tidbit closer now.
I'd rather you correct me than let me say something wrong.

With water alone you'll get "scratches" from a "hard" Jnat. If you get kasumi it's a soft stone. Also you can't tell a lot by scratch width eg dmt 8k may be 8k wide but about 1k deep

Yeah, "works quite well with razors" is different to "ultimate razor finisher" which could go 4 figures for an Oozuku Asagi.

That it works well with knives tells me it's more towards soft rather than razor level hard. At just under 3lbs tho, it's a lot of stone, even if it only works out as a pre-polisher.
