How to Maintain Naniwa Resin Bonded Diamond Stones

This is the 3k stone, feedback is low but makes a crisp 3k edge on high carbide steels at high hardness but the cut is weak.

I always learn something each time I watch your videos! Thanks for sharing!

[@southerncross100]

Thanks for sharing the technique.👍

[@KingJL25]

Hey there BBB, thanks for sharing this great info. You always teach me new stuff :) I have a question about the naniwa lapping plate you have under your stone holder. How do I maintain that? Mine is super gunked up and I can't get that soft stone powet out of there.

I just did the wrong way on a big flattening stone. (that big black one with deep diagonal grooves) Thanks for the video

[@user-xf4es7eh9y]

if it works, it's not wrong. There's 1000 ways to skin a cat in this game and everyone wants to think their way is the correct way. The correct way is whatever gets the job done. That big black stone you're talking about literally is black silicon carbide. it's the same stuff he's using in the video, except black SIC is actually a little less hard than green sic so it's even more "gentle." If you really want to be gentle with it, try getting a pink alumina flattening and lapping stone. They are becoming more popular than SIC flattening stones these days because they last longer and are better about staying flatter for longer.

I'm still in the Naniwa Superstores, my Arkansas's and KME still holding in fine. You are always my test pilot! I know you like to go back and forth utilizing a plethora of different stones. Are the CBN's that are out right now really that much better or are we talking steel specific, especially with some of the exotics you love to use like you currently are. Are Konstantin's Silicon Carbide stones and Venev diamond stones worthy of getting worth getting a couple of or what better do you have up your sleeve (because you always have an ace in the hole) so I use you as my investment broker still, if you think certain or newer stones out give more advantages, I want to know! You better be having a beer right now, I sure am!!! :)

[@FearNoSteel]

Those silcon carbide stones are very muddy and soft. Not my taste good price but wear fast and gouge. The venev is better for exotic steels, I liked the Naniwas better because the finish and edges are more consistent but sounds like there has been an improvement with the OCB stones. Vitrified bonding is my favorite because I get speed, feedback, finish and good cut but a lot more expensive than resin.

[@bp-hx9ts]

Benaiah Brabant I have excellent experiences with the sic stones not soft super muddy or soft a little bit softer then a shapton pro in my experience and not super muddy either don’t know if they changed it or if bbb got a prototype or something if you want to test out the sic try the edge pro set like 67 bucks and for vnev they have pocket stones that are about 10 bucks a piece in the new ocb bonded version

[@EdgeMasterPro]

@@FearNoSteel have you tried the chinese DMD resin bonded diamond stones. A fraction of the price of the naniwas. Which brands are vitrified bonding? This might sound like a silly question but do you think you could cut them with a tile wet saw and a diamond blade, I want to make some for my wicked edge.

[@robertmunguia250]

How much warranty do you get on those stones? Thinking of purchasing one.

[@MichaelE.Douroux]

Hi, what grit finishing stone were you using to clean the Naniwa resin stone? Thanks!

[@bp-hx9ts]

Have you tried the new vnev ocb bonded stones they solved the problems with the old ones apparently still pretty cheap think I might buy em

[@FearNoSteel]

I'm all about Vitrified

[@thehonfleur]

How long do these stones usually last? Looks like a very thin top layer

[@paulsargent8737]

What is that silicon carbide stone you used to clean it? And where can I get it? I just got some venev 1x6 stones and I was re profiling some cheap steel and the 80 grit stone is super loaded up now and I am new to sharpening so I don’t know much about how to clean it out. Thank you

[@michaelphillips8055]

been looking for the stone also

[@jasonandres6908]

I put a small gouge in my naniwa stone yesterday...surprised because I didn't think that was possible with diamond stones. Can I use to small lapping stone to get those out, or am I screwed?

[@CliffStamp]

When you get a diamond or CBN stone, it isn't a solid piece of abrasive, like you get with ceramic stones. What you will get is either : -a plate coated with diamond/cbn which is very resistant to gouging (maybe impossible unless you really try) -or a bonded stone If you have a bonded stone, you can actually flatten it, BUT, that's a lot of abrasive lost. I would ask are you really sure you want to throw all that abrasive away, can you sharpen with the gouge in it.

[@mikeisaac3826]

I’ve always wondered what would happen if I chamfered a whetstone with a Dremel. Idk if it would crack or be successful.

[@FearNoSteel]

Why though?

[@mikeisaac3826]

Big Brown Bear The edges of my sharpening equipment are a tad bit higher. Also for me it’s pretty much the first thing on a whetstone that gets higher than the rest of the stone.

[@KingJL25]

@@mikeisaac3826 You shall sharpen on the full stone, not just the middle. The higher edges are the number 1 sign, that you are not using the stone to the highest percentage possible. Just try and sharpen on the edges too (make longer sharpening push or pull strokes, utulizing the full stone). You should get a lapping plate/stone, like you see BBB use as a underground for his stone holder in this video. With it, you can grind the stone down

[@andrewocuinneagain4645]

Hi I've just bought a Diamond resin bonded stone & I'm just wondering what grit is the Silicon carbide stone used to maintain the stone? Thanks.

[@FearNoSteel]

220grit stone flattener

[@user-xf4es7eh9y]

why would it be wrong to lap the diamond stone with diamond? i mean in normal use it ends up releasing some diamond and that diamond rubs on the surface .if you for instance lapped them on plain textured glass, they essentially lap themselves by releasing grit and it's own grit ends up lapping the stone. thats how i've been doing it, just rubbing them on glass. with nothing but water added. it's actually a frosted glass so it's got a little bit of "texture" to it in that it's not smooth like normal glass. I'm not against hitting them with my worn out atoma in a pinch either. Is this wrong? seems to be working fine, works really quickly actually.

[@FearNoSteel]

Because you are only trying to cut the bond, you are not trying to damage the expensive diamond abrasive grain underneath. Diamonds don't just work because they are hard. They work because they also have sharp cutting facets on them like knife edges when they go dull they stop cutting just like everything else, So you cut the bonding around the diamond and shed the dull diamond, now you have fresh diamond that is being exposed which is not being pulverized by other diamond.

[@FearNoSteel]

Depends on the user and the pressure they use. There is no answer to your question, just like a tootsie pop. The spirit of your question is that you are concerned about longevity, unless you are sharpening 10,000 knives a year it will last a lifetime of use for home users. The stone will outlive you

[@larryseibold4287]

@big brown bear How does that included Nigura stone compare to a rust eraser for cleaning up the resin bonded diamond plates? I see a fair amount of color (rubber) coming off. i would think that you might want a larger lapping stone to prevent dishing in the heavy use areas over time?

[@FearNoSteel]

Pretty difficult to dish out 1mm of stone especially when it's super hard resin bonding, The idea is to keep the resin dressed rough so that the diamonds are more exposed so the stone actually cuts better

[@CliffStamp]

Yeah, you likely don't want a friable binder if you have diamonds, because the diamonds wear so slowly you would just be shedding sharp abrasive. However the loading is curious, it likely indicates their bond/abrasive mix is off, as you are seeing glazing of the resin. These are newish stones right? They likely have a too heavy bond mix. Do you use a libricant? IF, and this is a BIG IF, you can find a lubricant which is JUST light enough to reduce friction on the bond and NOT mask the abrasive it will help. But if you go too light it won't do anything with the glazing, and if you go too heavy it will stop cutting. But if you have time, and a way to get a variety of lubricants, it can be something to experiment with. The manufactur MIGHT have something available assuming they use these in power tooling, but that will be too heavy as it is designed for industrial pressure, not hand sharpening. So maybe start with what they recommend for the lowest feed speed and pressures.

[@ColossalSwordFormAndTechnique]

Bondage? 😂
