This series of videos in particular has been really useful. I managed to improve the whole knife and not just to sharpen the cutting edge for my cheap kitchen knife, by further thinning/creating another bevel. The changing scratch pattern was very helpful to observe the progress. Natural stones really seem nice, got to try Morihei and Imanishi finally, synthetic stones with mixed natural stone. Didn't know the feel to work the knife can be so nice.

Thanks so much! I use both Morihei and Imanishi stone and enjoy both ‘

Fantastic as always. I would love to see a classic edge sharping with no takes. Seeing the whole process of how you set the angle, how you take off the burr between stones, and a more general overview of how you sharpen would be so insightful. More of an edge sharpening tutorial. Think that would help a lot of people. Thanks for the videos.

Thanks so much! We haven’t done this type of video as there are so many on KZbin, but if it’s something a lot of people are interested in seeing we will definitely consider it. I don’t want to bore people to much lol!

@@ivanyuka-japan I think having it done from someone like yourself would be great. I’ve been sharping knives (mostly bought from Tosho) for years, but I’m still not comfortable enough to try most of the techniques you show in your video. I still watch to gain insight and love to see the mastery. However I think most people would like a good base before they move on to the more advanced techniques you are showing. Just my opinion tho. Will watch regardless.

Exactly the steps that probably a lot of viewers are looking for in videos like this. Myself included. Great comment.

Ivan an interesting technique I have used when sharpening straight razors and examining edges with a microscope, is sharpening with the stone under a lightly running stream of water. I was reminded of this when you spoke about putting the stone on a slight angle at the 15 minute mark to help drain excess grit off the surface. Have you ever tried this technique during your knife polishing process? It’s interesting how the surface of the stone can be the ideal grit level but then when the grit is loose on the surface of the stone excess scratching happens from clumps of grit on the microscopic level, I noticed a big difference in my polishing of razor levels with the running water technique finishing.

Hi, thanks and yes I have used this on both edge sharpening and polishing. I use this technique regularly when sharpening for Konosuke, using a Nakayama Kitta in this way with continuous water running. Gives a beautiful crisp edge one white and blue carbon steels as well as vintage carbon.

Phenomenal. Is there a chance for a single bevel sharpening video in the future? Or the discussion about beta togi and hamaguri differences?

@ivanyuka-japan 8 ай бұрын

Yes there is a possibility in the future. Quick note, Beta Togi is sharpening from Shinogi line to the cutting edge, often with no change in angle. And Hamaguri for a single bevel is convexed near the edge with/without a micro bevel.

@junior90210 8 ай бұрын

@@ivanyuka-japan thank you! I know the theoretical and some practical differences between these two styles of sharpening, but I'm really curious about your perspective on that - meaning what are she advantages and disadvantages o both and what's your preferred method. Some sharpeners claim that beta togi is practically impossible, because of the distal taper (the kireha is never 100% flat because of the blade geometry).

Great video Ivan! I agree on finishing I do the same and am quite satisfied with the finish. This is off topic but I thought you might know. I noticed that in the shops where they are doing many blades at once they have a green liquid they store the blades in to prevent rust and I have tried a couple times to find out what it actually is if you happen to know. The language barrier was such that I could never find out what it actually is. Thanks Bruce.

@ivanyuka-japan 8 ай бұрын

I know what you mean, I always saw it in a craftsman's workshop but never thought about the name, they just call it "rust proof liquid". I'm not 100% sure but it seems not for a knife, maybe for a car.

@@ivanyuka-japan I am hoping against hope it is not antifreeze cause that is what it looks like. LOL I shudder to think of putting my hands in it every day that can't be good for them. If you ever find out I would love to know. If it is not something really toxic I would love to get some. Thanks Bruce

Great video as usual. Gyuto looks more and more beautiful from episode to episode. I admire your skills and I am very impressed by the way you look at the blade and choose the effect you want to achieve on the stones. In front of me is polishing my knife on stone 3000 (Suehiro Ouka). After this stage, I will see what happens and what to do next. I would like to get Kasumi on the Ohira Kiita stone from which I have figerstones. Greetings from Poland, big Fan :)

@@ivanyuka-japan I'm glad to hear. After researching synthetic stones, I chose Suehiro. I like that they are not hard and leave a nice mud. My arsenal includes Cerax 1k, Okua 3k, Rika 5k and Kitayama 8k from Imanishi. Hard work is done on Shapton Kuromaku 320.

@ivanyuka. Your experience, knowledge and arsenal of stones are truly inspiring. I recently restored a deba and found gaps in my stone progression and in watching this series I know now I need more stones and to learn when to use what stone. Thank you for sharing your knowledge. This is truly a next level master class. I was inspired by a previous long format video you made where so foggy it looked unattainable. 🙏🏼

So u have to flatten a vitrified diamond stone? Or is that a different type of stone. I thought vitrified diamond stones always stay flat? I must be wrong.

@ivanyuka-japan 8 ай бұрын

These are resin stone, not vitrified. But all stones need to be flatten. Unfortunately there is stone doesn't need flattening even vitrified.

After being so involved in this Mazaki blade how did you like it? I’ve had another of Mazaki’s KU series gyuto but it didn’t really live up to my expectations also after being professionally sharpened

@ivanyuka-japan 8 ай бұрын

The blade needed a lot of work getting it straight and set up at the lower grits, but after this sharpening was pretty straightforward. First impressions seem to be a nice blade but the real test will be when the customer puts it to use so we will see !
