Very nice I am really enjoying this series.I think the cloudy areas you are seeing are hardness variations in the cladding material. Uneven application of the clay tempering medium can produce this and if done across the whole blade in a line can produce a secondary hamon which is quite beautiful.
@@ivanyuka-japan I hope you will continue your channel I really am enjoying it. I have been making knives since the late 70's and restore antique ones as well. Sharpening is my passion and I still experiment with different ways even now. I have been working on apex sharpening lately instead of burr formation to save all the steel I can on historical knives but still remove all the damaged steel but not waste any. I love making knives but sharpening is my zen time.
Yes, the final polish is always done lengthwise across the blade, during the rough sharpening I go back and forth between a more horizontal angle changing the and between each stone
I never use diamond abrasives for cladded or damascus knives because diamonds cut everything the same. meaning they dont bring out the contrast the way other abrasives do. Sometimes I can make it work if I introduce a lot of mud from a softer traditional stone onto the diamond stone or even paper, then this can leave very smooth surface but still shows that subtle and nice contrast on the clad line.
Yes that’s true for most diamond stones, NSK diamond can be used in multiple ways as they are based on how natural stones work, they can bring out detail in cladding or mute the contrast to see the scratch removal progress as well as scratch depth, useful for me when transitioning from NSK to natural stones.

Thank you ! Yes I believe you are right as I get into the finer stones the hardened areas remind me of hitatsura hamon I’ve polished before

@@ivanyuka-japan
yes nsk stone.
thx so much for your reply.
good dream!😎👍
Beautiful. I wonder what the core steel is like?
Thank you! The core steel I feel has a nice balance of hardness around 63 HRC and ease of sharpening, it gets bright quickly and easily.
Do u sharpen more at an angle (more horizontal) to flatten the low spots on the blade and more vertical, along the length of the blade when u polish?
Yes, the final polish is always done lengthwise across the blade, during the rough sharpening I go back and forth between a more horizontal angle changing the and between each stone

@@ivanyuka-japaninteresting I had never heard of NSK before. I will have to look into them. I hope you continue the channel and upload more!
