Re: Exposing the core

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

Re: Exposing the core

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.

Re: 5000 Nubatama Bamboo Video

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

Re: 5000 Nubatama Bamboo Video

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

5000 Nubatama Bamboo Video



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

Re: Exposing the core

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...

Re: Can this be fixed

"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.

Re: Can this be fixed

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.

Re: Fixing a tip

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.

Re: Closest stone to a King 1K that can abrade Vanadium Carbide.

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...

Re: Closest stone to a King 1K that can abrade Vanadium Carbide.

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.

Re: Limiting factor in edge acuity

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...
