I am so glad the RU-vid algorithm showed me your channel. I have gone in just a few short days and watched all of your videos. I have been studying knife making and finishing for a long time while I was in the Army waiting to retire so I can start knife making myself. I have recently started watching about finishing Japanese chef knives but they have all been in Japanese with no English. It's funny because I work in an aerospace machine shop making parts for SpaceX and Blue Origin and my job is doing the finish and polish work. Rocket parts that have to connect to one another have a polish requirement. Everyone asks why I am so good and it is because of watching videos like yours. I hope you keep going with the videos, I could just sit and watch you all day.
K, obviously this was amazing… but now I want more 😅. We need a whole series with Mark. A stone video, a kato kitchen knife video, tsukasa, Shigefusa…. More please!
really fine work but I feel that you overcomplicate and extend it into a lengthier more involved process than required to each the same end result and I believe this is simply because you seem to enjoy it. I
Thanks so much for the insight into my work, for me, my work is fairly straight forward and I continually strip down the processes and refine the techniques and tools used. So what used to take for example 5 hrs can be now done in 2hrs with greater efficiency and higher quality results.
If you mean on the Japanese natural stones Oli would be detrimental to the stone as well as other liquids other than water, due to the very porous nature of the stones.
Is there any chances that you'd visit the topic of polishing with a fundamental video? I've seen lots of sharpening fundamental videos but not one about polishing
Thank you for another awesome video!! I preordered one of your funaki knives and I’m beyond excited to receive it. Watching this video makes that excitement grow even stronger. Can’t wait to see what’s next!
Thank you so much for your enthusiasm and support! I'm glad to hear you've ordered a Funaki knife. Thank you for your patience, I’m working on it and hope you’ll like it.
HI Ivan, I love your videos and I really think that the content you put on the internet is extremely valuable to us knifegeeks around the world. I really appreciate the time you take to explain the different steps and techniques around what you do and what you are trying to achieve. Your polish is some of the best I've ever seen! Thank you again fror the effort you (two) are putting into those videos and I really hope you will keep creating content for us for the future. Kind regards from Bulgaria
Thank you so much for your kind words and support. It is an honor to receive high praise from you and it encourages me to sharpen my skills and make videos!
I'm upset that I didn't start watching this with afternoon coffee, it's the best time to dive in to a 40 minute video of interesting professional content. The after shots are truly showing an art form. It's beautiful. I swear that was the fastest 40 minutes I've experienced. I thought I was halfway through when Ivan said "this is the end of this series". This collection of natural stones is something like a library or museum collection. So many aren't split, cracked or chipped in a noticeably or major way it's rare for me to see. Usually you see only a few stones (speaking mainly of Japanese naturals) and even then they could be heavily split with very few being whole. The way of production takes me back to early school days when the teacher would show an educational documentary. The same vibe of comfortably casual mood and progression, but good information that's easily absorbed even for kids. It's a skill to be able to explain complicated professional stuff in a simple way. The visual production also supports so nicely the explanation. And the pacing is excellent. It's just an overall happy experience to watch it. A joy.
Every part of sharpening has its own fun points, but still it is definitely the most enjoyable part where all the hard work up to that point is completed in one piece!
@@ivanyuka-japan while not even remotely close to Ivan’s level, I share the same passion for sharpening/ polishing and usually my jnats tell me I have to go back to 400 grit 😂
Wow. Im blown away by the details and dedication u showed polishing someone else knife. Just out of curiosity, what was the total time u spent doing what u did for this knife?
I am a big fan of your work. I am 44 years old and two months in on my sharpening journey. There is so much too learn. Do you have any tips that you can share? 🙏🏼
I watched everything on this channel, some videos several times. Currently I am with my Nishida Daisuke Shirogami 1 gyuto on 400 - 800 stage. I received Ohira Kiita fingerstones from a friend - I wonder what the final effect will look like on my knife. It's my first time doing this and I would like to thank you very much for providing a lot of valuable information. I hope that my work will be at least a little close to what I saw here ;)
Thank you Ivan and Yuka - this series was most interesting to follow and watch. I have learned so much and it's a privilege to have a master like you share you skills to all of us 🙏 I especially enjoyed the video about blade geometry!
Hey Ivan, THX for sharing your experience. It would be fine when you're provide about the knives (which steel, HRC, ...) What do thinking, how many generations can use this giant aoto😂 and can you give us an idea about the cost (I've really no idea, but it looks expensive) and the last question, after you prepared the stones you've ever checked the flatness if the surface with an straightedge🤔 Cheers from 🇦🇹
Thanks in the first video of this series I provide the steel and details of the knife unfortunately I don’t know the HRC of the Mazaki gyuto I think the Aoto when I fought it was about ¥200,000, and yes I check all the stones with a straight edge as well as every thing else I’m using to flatten the stones
Amazing results. I'm curious what's the secret aside from +30 years of experience. 😅 When I'm polishing my knives, the kireha looks uniform/good up to 800-1000 grit. Above that (3000+) some strange lines and uniformities occurs. What may be my problem? Bad geometry on lower grits? To much pressure on higher grits? Bad techbiqye/angle? Mix of all the above?
Thank you so much! This video was - as always - really informative and enjoyable to watch. I appreciated many moments: the definition of the 'kasumi' finish, the different ways to achieve this type of finish, with the one obtained by jnats being the most difficult. The motivations and reasons for choosing different stones, the comments regarding the different steps are always relevant, and some information really surprised me, especially the use of finger stones which, contrary to what I believed, is not at all a standard step in knife blade finishing in Japan... Despite the richness of the content, if I had to express one regret, it's the absence of the part I was most looking forward to: polishing the steel with a different stone than the one used for the cladding...After 35" of "teasing", I would have loved to see Ivan demonstrate and explain how to proceed, especially on the questions of pressure and maintaining the angle, which are so difficult...Maybe in a future video? In any case, a big thank you to Ivan and Yuka for the quality of these videos!
Thank you so much ! Yes it’s always a challenge to figure out what to include in each video as they tend to get longer and longer. We will make a note of this for future natural stone videos
Thank you for sharing the process at each stage, showing the close-ups of the bevels. There's nobody on RU-vid at Ivan's skill level, so this is a treat for everybody watching the video. Great editing, great content. Please continue to share more content like this! 🙏🏼
