Here's my original 5k Nubatama video. Pretty.much of a splash and go.

I'll have to move
Those knife bends partially sharpened can be a mess to straighten out and sharpen.

I do. Lets chat on the phone. Pm sent

Of course ymmv. I found lapping plates hold up better than belts of all sorts. Indeed belt failures happen relatively fast. Ceramic belts seem a bit more robust but marginally so.

LOTS of feedback. Minimal dishing - almost none. Fast precise cutter.

Your biggest difference will be feedback and feel. Lots more. Reminds me of the 5k Rika but a higher true 5k grit.

Just came across this video. Its a favorite 5k stone. Reminds me of the Rika - just a bit finer and creamy.

Here's that video I referred to earlier:

Thanks all. I don’t need anything was just asking about time. I’m done. ... Just looking at it from a TVM (Time Value Money) perspective. Coarser grits = less time spent on a repair. Now that 46 grit plate does leave deep scratches so you have to look at that side too. Use the 140 Atoma to clean it...

"Any advice for grinding the bolster myself?"

Well get ready to scratch up the rest of the blade... and removing those scratches

And then resharpening the whole knife. Advice? Be patient.

Perhaps we are both wrong and need a third opinion lol.

You sound like you are in need of a 46 grit diamond plate ...

I'm still a fan of the black steel Nubatamas

Yes it can be fixed. DON'T USE an ekectric sharpener on these knives and DON'T take the knife to a sharpening service. If those are your choices just get a new knife. You will need to regrind the bolster and resharpen the entire edge which is a fair amount of work.

We cant both be wrong lol

You can do this entirely by grinding from the spine with a coarse stone. After, touch up the right and left sides of the knife which will probably have residual burr.

Well a 1k stone is equivalent to 16 micron and a 2k stone is 8 microns. so a 1.5k stone is inbetween - (16+8)/2= 24/2= 12 microns. FYI :) You could go either way if you wanted a more aggressive or less aggressive edge than standard or I can makes some 12 micron emulsion for you as a custom preparati...

Consider the 1k Nubatama Platinum hard formulation. Fast cutting. Cuts through vanadium steels well.

Another choice would be to use some 16 micron poly diamond emulsion ON one of your 1k stones to make it more aggressive on Vanadium steels.

Edges sticking to the board can be a problem. It is also related to thr cutting task. You see this with softer boards and depends on the knife used so usubas and kiritsukes are more vulnerable. You also see this with heavier blades like hunting knives which are twisted when used forcefully for baton...
