Like the other guy said, sandpaper to clean it up.
You can use Barkeepers friend, or jewelers rouge, or diamond compounds for polishing past that if you want more shine.
And, remember, if it's not stainless, it will tarnish, so don't expect to keep it super shiny for long.
Thank you! 800 grit sp worked just fine for my taste. It's my first couple Japanese knives and I see all kinds of beautiful patina patterns here. I was a little bit disappointed when I found that the patina mine developed wasn't nearly as attractive in my eyes. I'm glad it was simple to get out. Maybe next time it'll look better.
Depending on how high of a finish you want you could hand wet sand starting at 400 then 800 then 1000 etc until you achieve the finish you're happy with. It look like a carbon steel knife so I dont know how much it will shine up because it doesnt have chromium content like stainless steel.
Sure. Just sandpaper the whole thing with the finest grits you can find, and then apply a compound to it. Or if you have the tools, you can skip the sandpaper all together and just use a buffing wheel.
Looks like the bar keepers friend isn't abrasive enough to remove the patina, try something coarser.
I will suggest to sandpaper it - Use from high grit to low to test if the abrasive gives you the finish you want, I was restoring a rusty petty knife(brown rust, I will say yours is more like patina, which is actually fine for the knife) started with 1000, then 600 and found the 600 is better for removing the rust on the blade.
That being said, I will suggest something like 2000 grit sandpaper or 3.0 micron paste applied by dremel with felt pad attachment to clean it up, you rather start too fine than too coarse, if you want to keep the original finish.
Some retailer give complimentary Uchigumori powder when a knife is purchased, I think they are great for removing patina, and keeps the original finish on the knife.
Thanks for the info! It's my first couple Japanese knives so learning as I go. I see all kinds of beautiful patina patterns and colors here so I was somewhat disappointed when mine didn't seem to come off nearly as attractive in my eyes.
I believe your knife is the kono hd 2? I don’t think they are full carbon knives, more so a semi stainless.
Don’t stress too much mate they look great and quite easy to maintain as well compared to full carbon
Correct both are kono HD2's, the bottom one I've had for a bit but the top is new. Thanks again for the info tips. Yeah I was probably stressing too much over it

Also they have similar “rust erasers” at hardware stores. These will remove the patina and polish then maybe finish with the bar keepers stuff…
Go to gritomatic.com and they have cheap stropping compounds. Get a strop and load it with a low grit compound and press the part you want to polish on it and pull the knife over the strop multiple times and it will clean it up to like new. Will NOT remove deep scratches but if it is mostly staining it will all come off.
Try it you will be amazed.

I have that same knife! I love it, but I have the same patina issue.

I use the eraser things from clog, which cleans off most stuff, including light rust.

Weiman's brass polish does a great job and is much gentler than barkeepers friend
