TLDR: When polishing, the core steel on my non-dominant side comes out hazier than on my dominant side. What causes the mirror core? How do you consistently achieve a kasumi with mirror core steel?
Hello!
I recently spent some time working on polishing. I got some good looking (at least to me) polishes (especially on my dominant side), but I don’t really know what I am doing. I am left handed, so I have more experience polishing the left side. I was able to get good contrast with hazy cladding on both sides, but I was only able to get a mirror like core steel on the left side. The right side has some sections that are pretty reflective, but it is much hazier than the left side. The knife is stainless clad white #2. I used the following progression: Nanohone 200 -> SG500 -> NP1k -> SG2k -> JNS red Aoto -> Morihei 9k. Here is what it looks like:
Left side:
Right side:
I tried doing the same thing to both sides, but I got slightly different results. It makes sense that the left side is better because I am more comfortable/experienced on that side, but I would like to have the same results on both sides.
Do you have any ideas why the right side would be hazier? Where could I have gone wrong? At what point in the polishing progression is most important for getting a mirror core? Does it look like I didn’t erase scratches from a coarser grit, or does it seem more related to technique? How do you do it consistently? Maybe I will try some diamond paste on balsa like @cotedupy is suggesting in his thread.
I have some ideas about where I could have gone wrong, but I would love to hear what you think. Here are my ideas:
1. I don’t think that I made the right bevel as consistent as the left bevel, so in order to get an even finish on the right side, I let more mud build up on the stone, and I used lighter pressure. I didn’t have to be as careful on the left side. Would letting mud build up and using lighter pressure make the core steel hazier even with a 9k stone?
2. Because I am not as comfortable/experienced with sharpening or polishing right handed, my finger placement on the knife with my left hand is not as good, so by the time I got to the SG2k, I had worn through the skin on two of the fingers on my left hand. On the left side with the SG2k, I started getting a mirror-ish/more reflective core steel when I applied really heavy pressure on or near the core steel, but because of my fingers, I couldn’t apply the same pressure and get the same results on the right side. Would this prevent the core from becoming mirror-like on the right side, or should I have been able to resolve this on the JNS red Aoto or the Morihei 9k?
Thank you for your help! I really appreciate it.
