This is my Kiya 180mm santoku, Swedish carbon, pretty good feel and a decent performer. It's currently my go-to, especially as it's smaller than a gyuto and I've got a Korean kitchen with counter space about the size of a stove-top. I also don't worry much about what happens to this knife and have played with patinas, got it rusty, rubbed it all away, and so on again. It's kind of my knife to mess around with.
Anyway, I want to polish it. I can remove the patina pretty well with [I]Metal Glo[I] but you can still see some deeper indications of a one-time forced patina, former rust spots, as well as fine stratches in different directions from various abbrasive experiments. You can see a bit in the photos below.
I'd like to polish it up to look really shiny, not necessarily to a mirror, but enough to make it look new again, and maybe round off the spine a bit while I'm at it. For those who do this, I'm wondering what powders/compounds/finger stones/sand papers/micro meshes you've tried or'd recommend? I'm asking 'cause I'm organising a package from the US now and can buy this stuff. Have looked around, but haven't seen a definitive thread on this. (Maybe because patinas are popular )
Thanks for any suggestions!
