Thread: HELP!!! Please help verify if stone is Karasu

on the iyo; what does the other side look like? I find mine to be the same essentially on all sides. Maybe you can lap the other side

Try some thin CA in the crack regardless

i'm the furthest thing from an expert on japanese hones, but here's what i think based on what i consider a common sense

you made a mistake.

if you don't have the money to throw away you should not gamble on stuff that you have no idea how it will turn out. i always think that the best way to save money is to pay the extra for the expertise and ensure you are getting what you want.

from your posts it seems that you bid double the ebay seller's opening bid. i recently read a thread where he and his hones were discussed at length and it seems that his opening ebay bids are just the price he wants for that hone without providing any additional tests or guarantees. if you want these extras you have to pay extra and he will take the time to find a hone that matches what you want. but you have to contact him and arrange that. if you just win a hone from him on ebay you are not getting any of these additional services he is willing to provide, regardless of how much you pay.

the hone may be excellent, but i'd be betting that this is less likely than more (given that the seller actually deals in these in bulk and the stuff he thinks is top choice he sets aside, tests and lists for much more money on his website).

so, you just took a big gamble and more likely than not you overpaid for a hone by a factor of two.

I realize that's not something that's going to make you feel good, but that's my honest analysis and I hope that it may be useful to you and anybody else who reads this thread for any future purchasing decisions.

Sorry I cant be of more help but like I said before I am just beginning this journey.

I don't really get it, what wood? I just place a piece of tower underneath the whetstone when honing.

The other side of the stone look much better without any crack but smaller honing area plus the end of 2 side look like the base of my karasu.
What is CA? Can I just use any lacquer to fix the crack?
I will try to post some pictures later.

I spend the trouble creating this account and thread because I want to verify whether or not did I get the right product which I paid for.How did money and gamble came into place?

First of all, I did not place a bid on his ebay's whetstone because the stone I want is not there in the first place. I did contact him and ask for a quote razor size Karasu & Iyo plate. However, I did not know Karasu has so many grade even though they have the same name and yes, somehow I did not know what I had paid for in some way. Luckily, the karasu is doing its job just fine and I am pretty happy(just some fear that the huge crack will cause it to break into 2). So the problem has reduce to only the razor size Iyo stone as you can see I am asking for advise.

I do agree on your analysis but I think you make a mistake here.
Not trying to start any flaming war, please do not feel offended in anyway.

CA= super glue

Well it doesnt sound like your towel is too stable if the crack is growing. Even though it feels stable on the towel the crack is still growing which means the stone is flexing a little. If you permenantly glue the stone to a piece of wood the stone will not be able to flex and the crack should quit growing, that is as long as the wood doesnt expand or contract. It may be easier if the stone would just completely break in half,as long as it is a clean break, that way it would be very easy to get the glue or laquer into every facet of the crack.

I see...I will try out all the suggestion given.

Thank you guys for all your time and information.

I'm going to suggest you discuss this with the seller, as I have a several year history with him, and have been surprised and pleased with every stone so far, 5 if I remember correctly.

If there is a crack that is making the stone unusable, the sooner you tell him the sooner he can seek a replacement. I have bought a vintage Aoto from him after I'd purchased one elsewhere that was 'gritty' and borderline useable, and he delivered an UGLY old doorstop of an aoto that sharpens like a dream.

One thing to consider, the relative value of our currency vs yen has made prices in dollars go up 50% in the last 2 years. If you want quality, bring money.

My largest hone cost < $400 3 years ago, and I suspect over double that now, as it improved greatly after I received it. A thin layer flaked off the bottom and exposed a surface equal to the top side, which I lapped and now use regularly.

There aren't many Japanese hones useable on both main flat surfaces, and I've gotten 2 fully useable out of 5. I'm feeling guilty because my good fortune is so different from your experience. You can consider that every stone so far has been a keeper, not for sale, period, at any price. I very much hope you wind up with one that pleases you as much as mine please me.

Talk to him. I think he cares about stones a great deal.

I have already discuss with him before I start using the stone and he did give some advise on lapping the stone. I find that sending the stone back for exchange would be too much trouble plus the shipping will not be cheap as the stone is very heavy. Actually, the amount I paid is more than double on the ebay listing. When I double up the ebay listing price for a good Karasu, he quote that as "fool" which made me kinda angry

Now trying to lap the stone flat for usage. Karasu is not giving me any trouble other than the crack by the side which I kinda mind. Might sell this one off and buy another one with a flat 6 plane though.

Thanks for your suggestion anyway.

OK, my mistake, I thought you did.
Buying something you don't know much about without trust in the sellers knowledge and integrity, and/or having to rely on a third party to evaluate your purchase = gamble.

Good, because that would not be a good thing.
