Thank You very much. This is exactly the kind of video I need. I love watching you at work. Yesterday I finished watching a series of 5 videos about polishing a knife for the second time. Greetings from Poland.
It's really nice to see this. I'd love to see some more insight about identifying the shape of the grind of the bevels and how to restore them after doing a thinning process, just like how the hamaguri was identified in this video. You can find a lot of information about thinning and it being something to do on the internet now, but not often the precise dialing in of the shape of the bevels and how to see and work them to get cutting feel you want or match the bevels that were initially there from the maker. It's a bit difficult to figure out.
I'am actually forging a gyuto currently so these little details are very useful for me. Thank you very much for sharing your wisdom with us all godbless and good health.
Your support means a lot, thank you! It’s awesome to hear you're enjoying the videos. I'll work on putting together a comprehensive video on that topic.
I'd love to hear more about fixing geometry etc. Most youtube sharpening focuses on exactly that: sharpening. But Ivan does the whole process, starts from reviewing the blade in general, is it bent, how does it fare when rocked on a flat surface. A lot of people in my opinion can understand making the triangle point by sharpening, but how about recognizing and fixing things like when Ivan fixed the knife on the five part video series with thicker and thinner parts and straightening it. I wonder how complicated it is to straighten a blade that's bent and uneven in multiple ways? Like bending one in shape probably changes the context for those other deviations. And how does it differ from when you for example sharpen the edge asymmetrically by accident and it goes into S-shape, as compared to the whole blade being off in some way? How do you work the knife with your mind focused on it when it has these other issues like having to remove parts of the bigger bevel. Like avoiding making it worse in some way, but in fact beautifully even. I assume this whole preparation makes a big difference in how the knife performs, compared to even if you were a great sharpener and didn't do the preparation. I believe those being more about technique while understanding where the geometry actually is and where do you want it to be, is it correct? I notice this video already addresses quite a bit of that process of recognizing what's going on with the blade and how to do it. Great videography in terms of getting some of the sights to show up for the viewer. Helps understanding how it looks like. I also really enjoy Ivan's calm and coherent narration. I'd gladly listen to long format like 30-60 minutes of him explaining some important pointers that come from professional experience, sipping my morning coffee. The sound effect for notes when he looks at the blade, I was thinking he rubbed the mic every time until it happened consistently enough. Watching him bend the knife made me realize just pulling a cheap knife from a block rack probably bends the blade slightly out of shape already. Very much looking forward to the next videos. Also would be happy to hear an initial analysis tied to what issues and operations would relate to which part of the process. Obviously you don't fix everything at the same time.

Would it be possible to describe the two steps you take to prepare the Oboro Knife 200 Grit stone, starting at 13:50? It looks like you use two materials to scrub the top of the stone.
We use NSK Kogyo’s 200 grit flatter for flatten the surface, and to make more aggressive textures use 120 grit rough stone, both you can check Komon’s website This video down below would help answering your questions individually, we shot both of the process Basic Tip of How to Use OBORO KNIFE - NSK Kogyo th-cam.com/video/b9ShvSxELrE/w-d-xo.htmlsi=ogmNTXat1NQT-qNO
Great content! If possible, could you please do a video on burr removal? I really struggle with that part of sharpening. I have a great, really sharp edge when I get lucky and remove the burr but usually can't seem to remove the burr unless I raise my angle for a couple of passes. Thank you kindly
Thank you for your feedback and suggestion! Burr removal can indeed be a tricky aspect of sharpening. I'll definitely consider creating a video focused on this topic to provide some guidance and tips. Stay tuned for future content, and I'll do my best to address your question thoroughly!
How do you correct for unevenness in the blade thickness. Where you grind through the edge at one point, but have more thickness before or after, lengthwise?
This is fairly complicated to explain in txt but after I get the blade straightened the main work is then to even out high and low spots in this case the blade road, I start with the high spots first working outwards, at the same time I will correct the edge geometry and establish a microbevel to gauge the thickness and evenness across the area of the blade about 1cm behind the edge, when all the problem spots are correct then I start blending the entire blade road together, all this being done on a 120 and 200 grit stone. After I check for an even and consistent blade road using light and a straight edge and digital caliper I’ll either continue on with blending or move on to the next grit 400 Hope that helped to answer but it’s probably something only understood in person
Very useful vide, thank you. Already the scratch pattern of the 200 grit stone looks very decorative.
Thank You very much. This is exactly the kind of video I need. I love watching you at work. Yesterday I finished watching a series of 5 videos about polishing a knife for the second time. Greetings from Poland.
Thank You very much for sharing of Your working skill and process! Looking forward to another videos.
ah! i was so looking forward to the rest of it!
Thanks a lot to share your knowledge! Waiting for the next video.
Can’t wait for the next step!
We are just shooting it now. Try to upload next weekend!

Thank you, yes this is very important and part of my daily work, we will take not of this and include it into upcoming content.
Great insight! Thanks a lot!

Great thank you - that's what I like!
Already a great knife, but imagine how much it has been improved.
Can you recommend a sample progression of stones for a high carbon steel knife, Rockwell hardness 56-58, 440c?
love your videos, you do a amazing work
could you do a video teaching how to shape, angles and everything
Your support means a lot, thank you! It’s awesome to hear you're enjoying the videos. I'll work on putting together a comprehensive video on that topic.
Thanks to share Ivan
Thanks for your content. Really helpful. Big fan.
Thank you!
Great video looking forward to next one!
Hi Ivan and Yuka, it's always nice to watch your videos. Can't wait to see the next one as I have yanagiba hamaguri waiting for some work.
Nice video, i just finished grinding a Nata today. I think some content about these tools from you would be great
Thanks actually we are planning to sharpen a Nata next time we find one in the Kyoto antique Market
Great video
