Norton India combo grit shedding problems, defective?

Hey there, by suggestion from another forum member, after I did some commenting on old threads I decided to start my own. Hopefully this helps someone out there experimenting with a Norton India oil stone!

Bought an IB8 to compliment my new found love for Arkansas stones, and I've had some mixed thoughts. When using the stone dry, and sometimes with water, I get excellent results JUST off the old Nortin India combo. I see why people like this stone so much... mine is the newer Mexican made version, and did NOT come in the "Anniversary" package.

When I apply Norton oil to the stone and start honing, I get sludge, and HARD grit particles leeching from the stone. I understand this can be normal when the stones are RIGHT out of the box, but this stone is WELL broken in.

When using the stone dry it really is a great tool, but it loads up like crazy, then you have to mess around trying to clean it. Perhaps I will boil the oil out of this stone at some point: here is a video showing the problem I am having-Watch the video to the end, hence the last minute or so is where you really start to see and hear the issue! Thank you!

I watched it, --- couldn't see it, -- couldn't hear it? It looked normal as with my Mexican made Norton India stones. Maybe a little better. Rest the camera on something. The knife looked as if it had been sharpened a lot. DM
 
I see nothing wrong.

The stone will shed some grit but not like it was made out to be from the original statements. If it didn't release at least some grit then the stone would become dull and unusable.

I just tested mine out on a kitchen knife like yours, after a minute I too had random bits of grit in the slurry. This is 100% normal and how the stone works. It does not shed grit like the SiC stone or even a waterstone. Both yours and mine act exactly the same way and it's how they should perform.
 
Did you watch in 1080? You could not see that little shimmery thing on the knife towards the edge? perhaps I should highlight this. You did not hear the insane level of sandy sound towards the end?
When I sharpen with that sandy crap my edge starts to reflect light again.
Hopefully you watched to the end like I asked you guys to. n
The crystals may appear as air bubbles on the scree, but they are indeed solid pieces.
GO TO 4:47!!!! you can clearly here it there
Yeah that knife is just a practice knife, its meant for experimenting! haha.
If its normal this stone is worthless, because I cannot get a good edge off it with oil, dry works 10 times better.

The fine side is rather coarse, it always sounds and feels sandy when sharpening with oil.
 
Mine will develop a bit of raspy when used with oil, and if I let it dry out a bit it runs very "clean" and smooth sounding for the last strokes. I let a film of oil sit on it when done, wipe off after a few minutes and the stone is satiny smooth and very clean.

Most of the junk in the slurry is swarf. After doing a whole bunch of knives with it, I do not get hardly any grit in the slurry - have wiped it off on paper and it will not work well for a stropping compound, so the amount of lost abrasive material is very small compared to the amount of removed steel.

I second my recommendation to condition the surface with oil and a file - nothing crazy, just work it down so there are no high points and it should come around nicely.

Another thought, some of the sandy sound may very well be the burr being worked back over/down. I couldn't tell from the video but it seemed like the edge might be generating the sound, and not the stone grit. Perhaps sound is worse when hitting slight recurve at the heel of the edge? I'm not discounting anything, just exploring all possible avenues. As I have been taught at work, always assume operator error first - mechanical/software second.

Next time it starts up, wipe it off on clean sheet of paper, blade and stone surface. Let it sit for a few and check it after the oil has migrated out and the paper is no longer wet/shiny. Then you'll get a good look at whatever is there.

We are close enough I could exchange my US made one with yours and give it a try, I'd still condition it with a file B4 any other action.

Well i've tried it with many knives, i'm done a lot of stuff to it... a couple guys on youtube commenting saying that their stones do not do this.
HeaveyHanded dude I would glady drop this stone off in your mail box and let you give it a try and see if you can come up with anything. I would appreciate that.
If not i'm probably just going to buy something else. I would love to try your US stone! Let me know on my youtube page if you would be down to do this Heavyhanded.
 
Seems like you got a bum stone. I couldn't tell from your video, everything looked normal. I have a Mexican India stone and no matter how I try to talk myself into "better" stones for me this thing always gives me very sharp edges. Will be interested to see what Heavy-handed has to say about it if you get the stone to him. . Good luck
 
Thanks for not doubting me too Etap haha. I thought you could hear and see what was happening on the video pretty well but I guess not...
can you see the little crystal on the knife when I say "here you can see it" ? It looks like a little air bubble near the edge, but its hard as a rock!

If this is just how Norton stones are, I guess i'm just picky! I ordered a medium India stone, it should be here this week, if it reacts the same way then i'll know its just the way they are!
 
Listening to this video with headphones on was painful. Those sounds were pretty awful. Maybe the guys who can't hear or see anything wrong are using speakers instead of headphones? Or low volume? It doesn't seem like normal behavior to me. But I'm realizing that I've never used oil on my India stone. I'd offer to test it out, but I don't want oil on my stone. Did you say water did this just as badly? If so, I can try that out in the next few days and report my findings.

I sent you an email to the address on your profile. You could swap out for a few and I'll give it a run through - send an email.

Yean man its painful sounding I agree. Water isn't as bad, but it still does it a bit. The problem with water or dry is the pores of the stone loads up, so I kinda wanted to use it with oil is the thing.
 
I replied to the email you sent me my heavyhanded, hopefully you get it, or do I need to sent it to a different email? thanks bud.
 
USA Norton was great Heavyhanded, appreciated it. Seems as though you got my stone working quite well too after conditioning it for me!
Cheers n beers!
 
What did Doctor Heavy Handed prescribe for the malfunctioning India stone? Treatment with a tile rubbing stone? Or maybe the Doctor's famous "side of a cutoff wheel" technique? I hope the patient was not subjected to the sidewalk. Doctor Schwartz frowns TERRIBLY on this.

:) :)

He scared the stone into shape, otherwise alternative fate ain't pleasant for the stone

I literally laughed out loud reading this and seeing the picture. Good one Bluntcut! The stone even looks to be the correct color.

hahahahah! thats awesome! No I believe he got it going with just SiC lapping of different grits.
That picture is perfect!

That's what happened to the last stone that didn't pass muster - I got no time for no-hackers!

Makes me want to shave my hair again....and get some safety glasses.
