thank you @Jakeonthekob
2 hrs work more or less, 10-15 minutes each step.
I did the same with a misono ux10 270mm slicer

My fingers were aching just looking through the pics. Well done. isn't the brand mark just print screened on? or is it etched... how did you prevent it from sanding off?

@kalaeb
this is the first time this knife got a polish job, so I guess not enough metal was removed to get to the mark.
I started with 400 grit to make sure I get the deepest scratches removed, also made sure to wash and wipe constantly so I get a better visual of the progression.
this way I was only removing what's needed in order to go next step.

The brand mark is deep enough to stay undamaged, it's not so dark anymore but also this is a 13year old blade.

my next project is a misono 440 Honesuke 145mm.
hopefully, i will have some time next weekend.

Sure wish there were a faster way absent a belt sander!

Nice work !

The fastest way I've found is using a buffer. I use diamond bars, especially on the more abrasion resistant steels. Grit, cimpounds and wheel types will depend on the steel and scratch depth. You can also use a belt for some of the work, applying differential pressure around the Kanji to minimize it's removal.

Buffers in particular demand respect and are potentially quite dangerous.

Thank you,
about 2-2.5 hours,
if the knife is in a good condition usually don't spend more than 10 minutes at each grit, even less on the higher grits.

Thank you very much,
I can only imagine how easier it would be with a belt sander, unfortunately, I do it all in my kitchen, I don't have a workshop.

Btw I love the CBN emulsions.

Glad you are enjoying my CBN emulsions!

Mark has recently added 8 micron CBN emulsion from my product lineup. This allows sharpeners to use 8 micron or 2,000 grit CBN either instead of a waterstone or ON a waterstone or strop. Especially useful for dealing with abrasion resistant steels - or 'regular steels too'. For coarser grits of CBN - 16 30 46 80 microns, just contact me directly.




I use belt grinders, but use buffers for refinishing blade surfaces. Here's a video showing the use of a buffer using diamond bars. This is a small but powerful buffer. I have customers using this in their apartments, for both knife and straight razor honing and restoration work.

Love the sequences of images and grits. I finally had my first successful use of sandpaper (previous uses were less than successful)—I realized I was not using a LOW enough grit. I had remember reading many standard finishes were around 1k or so, but it wasn't until dropping to 400 that I was really able to achieve a smooth, natural finish on some blades than needed a little cosmetic work. From there, it is easy to go up a bit to minimize the look of scratch patterns (while maintaining a hairline finish) without turning the blade "shiny" or mirror. I was very happy with the results. Your post makes this clear, and it also helps to show just how high you can go.

I was excited because one of the knives was a Richmond (Kurosaki) laser petty. I was able to remove the faux blade road finish pretty easily at 400 without deep scratches that a stone would have produced at a lower grit. I think the knife looks a lot better...way more bad a$$! And it got a bit of thinning that it needed, too. :)
