Thread: Shaving off of 8K

I totally agree with this. I've always found that the bevel was to blame when I'm having trouble.

If you look at just this forum, not even advanced Honing, and hit the page finder that says "Last", you will go back it time to 2005 when .com forum started... The posts, talk mainly about two stones, either a Coti or the N4/8 there are soooooooo many tricks to getting the most out of both it will scare you...

That is just one of 1000's

Have fun back there...

Heh. I have a feeling that a lot of the stuff said in those posts gets "rediscovered" every once in a while by newbies (not me... I was born skilled).

IMO. 80 percent of the work should be done by the 8k number. Adding something afterwards can net anywhere from another 10-15 percent, and everything else after that adds less than 5 percent, with each successive hone doing less and less. The edge I get off of my Naniwa 12k is just as "sharp" as the edge I get off of of my Nakayama, all adding the Nakayama does is make the edge feel a bit "different" (in this case smoother).

In short, that edge off of 8k in 2005 was just as sharp as the edge off of (whatever) in 2009, just a little less refined. That said, we all love refinement right .

Can anyone verify that a King 4K is the same grit size as a Norton 8K? And if so, what does the King 1K equate to in the Norton range?

Would I be correct in assuming that since the King stone is Japanese, the grit described is therefore defined by the JIS system? If so, I need to find me something to fit in between their 1K and 4K. Also, roughly where does the C12K fit on that chart?

I can confirm that king 4k is perfectly shaveable off of. Did it this afternoon. I'd do it again tomorrow, but my swaty arrived... and after a half hour lapping, it's finally up to snuff... interestingly the "Dimo-grit" that also arrived today took all of 5 seconds to lap... that stone is SOOOOOOOOFT.... It was just shedding grit with the slightest shiver.

You shouldn't need anything between the 1K and 4K, it's not that big a jump and I did some decent honing with that particular combination. Good luck!

If I am reading this correctly the Norton #8000 is approximately equevelent to Shapton Pro 5000 grit? Does the new JIS also include the Naniwa Super and Chosera Stones? Placing them also around #5000 when compared to the Norton #8000.

Would I also be correct to assume that the Naniwa #10000 and #12000 Superstones would be around 0.9~0.5 micron? The Chosera #10000 would also be in this range?

Naniwa follows JIS--JIS is an extra-industrial standard organization, and they simply set up the grit size that industries in Japan follow.

There is no JIS above 8K, according to Naniwa, so every company has the leeway to set up their own grit size for 10K, 12K etc. and they are apparently company secrets...Shapton is unique in that they print the size on their glass hones.

I don't think the 10K/12K are actually quite so fine, but I don't know.
