Great as usual. Hopefully, we could watch a long version of sharpening processes without much words. Instead, sounds produced during the process, images from different angles, a side view which would allow us to pay attention to your beautiful, stable stroke (angle & pace/rhythm) etc. Not necessarily with special knives, but ordinary ones would do (personally, "ryoba" yo-bocho would be very helpful.) Many thanks!

音を聞き入ってしまうのですが…😂
今、個人的に1番ハゼやキスを開くのに小さい（ペティサイズ位）物を研ぐ動画が見たく、もし機会があればお願いしたいです😊

Wow! I'm not an expert but combination of difficult steel (Honyaki) and shape (very long and thin Fuguhiki) looks to me as PARTICULARLY difficult combo. If I wanted to do same with never mind half, quarter of that speed, I probably would make 10 micro chips from fingertips I cut from my fingers alone, no to mention maintaining geometry of that long Shinogi and Sori, straight and crisp. I must admit I was close to get heart attack when I saw this Honyaki run on 200 grit with that speed at first. 🤣 It always amazes me as I see professional sharpeners constantly look at blades. I mean I know why. They want to see what stone just did. Problem is, me, unless I color entire surface of say Kireha with marker, I look and see NOTHING. I mean I try. I clean mud, look, look, everything looks the same 🤣
