Making sure you have water in with the stone during curing is the most essential part. When I did mine I forgot to do that and it never cured until I did add water but the fumes from the urushi lacquer is staggering may even cause brain damage (I'm sue you said that once). Nice stone and another great video..
Thanks Guy, I learnt a lot making this video, don't use manual focus, don't let the camera strap hang in front of the lens etc. Quite a painful experience but now its done I can move on with my life :) I remember your stone it turned out well.. Thanks again.
I’m surprised that Kato would have stamped a stone with a cracked surface like that but then again I can only refer to the ones I’ve seen. I once tried the urushi route but hate the dark colour of it and struggled to get a smooth finish I was happy with….much prefer cashew lacquer. Tried clear coat paint and spray but always flakes off eventually…. Good video though and good job with the finger stone type paper use….very authentic method…..
Hi Hadi, I think this stone was once much thicker and my surface crack was internal, hence only half of the stamp. What are you referring to with "finger stone paper"? Many thanks Joseph
I can appreciate what you are saying. Looking at the stone I’m guessing it’s not overly hard but doesn’t need to be as it’s super fine and will provide wonderful feedback during honing without getting muddy. I was referring to the use of paper as is used with finger stones in katana polishing….
Same kinda bottles i use for honing. Fine mist and doesn't over spray, small enough to not get in the way, but just the right size Jnats are special, i am sure your agree 😉
What an amazing video. I like the approach of doing as you find fit (have never seen cement used to fill in the stone). I've been searching for videos like this. Where did you get the laquer from (pure and translucent)? Can this dark drying color be altered into something a tad bit lighter by thinning it? Thank you Joseph for the video.
Hi King, I did make it up as I went along to an extent and learnt some things along the way. The lacquer was bought from Mejiro Co. in Japan. Good prices, service and helpful. The translucent is lighter and you can thin it. One technique is to apply sparingly and then wipe off with a cloth leaving a thin layer behind. Many thanks Joseph
Joseph, do you know a good way of getting rid of the scratches on the side of a JNAT that may ruin the edge of your razor? Thanks for posting the video!
@@EdgeDynamicsEnglishRazors there is some waviness on the edges of the Ozuku JNAT I own is what I was trying to say, so that the passes with the razor become a silky smooth experience. I would also like to get a mirror-like surface on my Ozuku to make it shiny like your Nakayama. You did an amazing work indeed!
@@MrSilvestre587 You need to lap the stone flat , there should be no waviness . I always recommend the DMT 325 Diamond Plate.. My shiny surface is just water. You do not need it shiny. You can rub with a nagura stone to create a shiny surface if you want . Many thanks
Hi, These stones are sedimentary and can be unstable to a degree. Sealing the stone stops water from soaking in at the sides and it also creates a protective case. Untreated, pressure at the sides can cause layers to separate. Thanks
@@EdgeDynamicsEnglishRazors Ah okay, that makes sense. I've never used natural stones, I just use my stones for sharpening so I have ceramics (mostly sigma power).

Congratulations, the stone has become much more beautiful !
Thank you..
That was really interesting. Good stuff Joseph. Thanks for sharing.
You are welcome. Much appreciated Tath.
Great video, extremely interesting. Thank you Joseph
Thanks Roy,
I thought it was a waste of effort until after hours of editing I was quite please :)
Cheers

Fascinating video, really well done.

Thanks Trunker.. Glad you like it. Cheers.
nice video with everything well explained. I'm going to try it with one of mine too. thank you 👏🏻😀
You are welcome.
Thank you.
you should use epoxy instead of cement in this case. It will become so much more beautiful and perfect
Good Idea.
Thanks

Jnats are special, i am sure your agree 😉
Those bottles are something something to do with lizards & humidity..
I think these stones are very special. Beyond dragging steel on a rock..
Cheers

Hi Felix,
I do not quite understand. Do you mean toxic lines? On the jnat surface.

I missed something. Why are you lacquering a water stone?
Hi, These stones are sedimentary and can be unstable to a degree.
Sealing the stone stops water from soaking in at the sides and it also creates a protective case. Untreated, pressure at the sides can cause layers to separate.
Thanks
@@EdgeDynamicsEnglishRazors Ah okay, that makes sense. I've never used natural stones, I just use my stones for sharpening so I have ceramics (mostly sigma power).
How wide is the stone up to that crack?
67mm give or take a tad.
what's your favorite stone?
That is a tough question. Choosing a favorite child would be easier :)
Почему бетон а не эпоксидная смола?
Можно использовать эпоксидку. Бетон просто добавляет воды, никакого беспорядка, и он тяжелый.
