🏠NSK Kogyo Diamond Sharpening Stone - Komon
komonjapan.com/collections/ns...
We recently had the opportunity to try out a 100,000 grit diamond sharpening stone from NSK Kogyo, a company I've always trusted for my sharpening needs. This ultra-fine grit stone was originally produced as a test product, and I was fortunate enough to be able to borrow it for a special trial.
In our previous video, we focused on sharpening with the Hakuto 400, 1500, and 12K grit stones, meticulously evaluating each one. Now, in this installment, we delve into the 30K, 60K, and 100K grit stones. This sharpening on this video was only for an edge check test, not such as the quality of sharpening Ivan does usually. So there may be some rough edges, but please let that go.

今回はNSK工業の試作品である、100,000番のダイヤモンド砥石を使った研ぎの第二部です。
前回の12万番の研ぎの続きです。30万番、60万番、100万番と研ぎ進め、それぞれ仕上がりの違いをテストしています。製品として完璧な研ぎというよりは、あくまでそれぞれの違いを見極めるための仕上げのため、多少粗い部分があるかもしれませんがご了承ください。
今回の試作品をお貸しいただきましたNSK工業様、いつも本当にありがとうございます。

No doubt he is truly a master of sharpening steel. Placebo is strong in this video tho. Love and respect from 💙💛Sweden 💙💛

@goncalovazpinto6261 Месяц назад

Could have done a blind test... Also, I'm thinking the different slices had to have been cut with some time between each because he used the same knife and had to sharpen and film between grits, so I wonder how much this affected flavor and texture. There's nothing wrong with enjoying sharpening to a million grit, but these guys pretend they are testing the differences and they really aren't.

@HalfInsaneOutdoorGuy Месяц назад

The problem with softening the stone is that the particulates from the stone become suspended in the water, and your extremely fine apex bumps into them and dulls.

personal question: what is your favourite knife and what type of steel do like the most?

@antonc81 Месяц назад

It’d be interesting to see some apple slices cut with edges sharpened to different grits and comparing photos of the slices at equal timing post slicing to compare the rate of oxidation.

@ivanyuka-japan Месяц назад

Great idea !

@jakemosher215 Месяц назад

I believe you had some Placebo going on in your taste test. Considering the fact you knew exactly which grits you were tasting at the time if the test were blindfolded and somebody else handed you each peace to eat not knowing which grits they were you would not have the same reactions!!! But a very interesting sharpening video.

@user-xf4es7eh9y Месяц назад

You mean a non blind single sample size "taste test" is not actually a real test? Wow. That's offensive. Cmon man. Embrace the mythology and woo woo.

@ivanyuka-japan Месяц назад

Yes I thought about that, but after we finished the video lol! Next time

Ivan: This has been a fun series to watch I would be curious to see how other steels respond to these stones. I have been sharpening since the 60's and as I am sure you are aware found that some steels respond much differently to different stones. Some that work well on one steel don't do well at all on others. I would love to see that 100,000 grit used on one of my favorite steels to make my knives with AEB-L with it's very fine grain structure I think it would really respond well after all AEB-L was designed as a razor blade steel.

I imagine with the 100k it's so difficult that you have to consider even the cleanness of your fingertips and any debris from removed material. Great production in terms of audio clips and video clips of the tests. Probably the best I've seen on youtube, really well thought out. Now I get the idea of ninja movies where the blade cuts through anything without making a noise and people are unaware they've been hurt. These carrots and tuna really experienced that. Do you think this edge could last in a kitchen? Not in rough work but if you did some work like these test cuttings, would it hold the edge and would you need to be careful about your cutting technique?

@ivanyuka-japan 2 месяца назад

Thanks for the great insight into our content, definitely this grit range is over kill for most pro kitchen work but for Sashimi and Kaiseki I can see a great benefit.

@lone-wolf-1 Месяц назад

That's high level sharpening mastery!👌 I just started sharpening my knifes on wetstones (cheap knifes, up to 5000 and Arcansas stone) , testing different grinding movements, but still struggling with consistency... Also recently with stroping on leather, testing different polishing compounds. (and overdoing it too) I noticed a increased slicing resistancy on carrots with high polished edges. It sticks initially more than with the roughness of 3000- 5000 grit. (On hollow grind even worse, the vacum build under polished blades is hindering a effortless smooth cut. Want to try some rifling, or some fake damascus pattern) That's why I wonder, if you liked the bite of 60000 more that 30000, if it's in parts because of the higher sliding resistance of a more polished metal surface on the finger nail...feels like same bite, but smoother

NAIL!

@dredd3964 Месяц назад

The sharpening problem of all times and in all coutries on this earth is allways the quality of steel = the size of its "grain structure" in the metal mesh. For 99% of steel the grid of 1000 JIG is enough, because by this quality you could see the cristalls structure without microscope. After 10 cuts you will have micro-saw-effect on the border of the individual hard cristalls in the metal mesh, again. Getting sharp is not the same as keeping sharp.

@G.V.82 Месяц назад

fantastic simply fantastic, who makes these stones? I'm a keen sharpener but my finest stone is a 30,000 grit Shapton. I haven't found anything finer on the market.

@ivanyuka-japan Месяц назад

Thank you! These are made by NSK kogyo diamond stones, unfortunately for now these are just prototypes

@KevinsDisobedience 2 месяца назад

Man, I rarely go above 3k (Green Brick of Joy), so this was crazy to see. When a strop is scratching your polish, you’re getting up there at scary sharp.

@ivanyuka-japan 2 месяца назад

Yes I was surprised myself that the leather strop was causing scratches

Great video, can you show us how to do a full surface kasumi?

@user-xf4es7eh9y Месяц назад

can not be done with diamond. natural stones are the "real" way to do it.

@ivanyuka-japan Месяц назад

Yes I should be covering some aspects of a Kasumi finish in some upcoming videos

@user-bh8vx6lj2f 2 месяца назад

Why might some sushi chefs prefer to cut with honyaki blades? Is it because of the smoother polish on harder steel that disturbs the meat less?

@ivanyuka-japan 2 месяца назад

Most Sushi chefs I have spoken to tend to like the more rigid feeling Honyaki

Hello, is it possible to make a series about the sharpening itself with live comment about finding the angle ect. ?

@ivanyuka-japan 2 месяца назад

Hi thanks this type of video idea is something we are considering

@mijzelfmaardanik Месяц назад

That would be great ! There are a lot of videos around about sharpening, like instructions, etc. I really want to know what is going around in the mind of an master sharpener when being in the process of sharpening.

@RubricoA. 23 дня назад

can you test both. the 100k stone vs 100k diamond emulsion like gunny juice on basswood?

@ivanyuka-japan 23 дня назад

Sorry could you tell me which diamond emulsion you mention and the blade to test or straight razor?

@RubricoA. 23 дня назад

@@ivanyuka-japan Gunny Juice .25 micron vs NSK Kogyo Diamond Stone. Niko's Crucible Wootz steel blade. I want to know if there's a difference between a 100k grit diamond stone vs 100k grit diamond emulsion in terms of slicing aggression and longevity of the edge.

@ghlscitel6714 Месяц назад

What type of steel are these blades? What bevel cutting angle did you choose?

@ivanyuka-japan Месяц назад

This is a modern made Wootz blade you can see the details in part 1, angle I would say is about 10-13°

@ivanyuka-japan thank you. Your channel is a wonderful nd calming experience. Watching the sharpening series was incredible. Truly embodies the japenese tradition of doing 1 thing to exacting precision and pushing boundaries of the the human hand eyes and spirit. I would expect nothing less. God bless.
