And for under 75 you have alot of film and a surface plate.

How many laps are you doing on your 30k to get micro-chipping ????

I dont have a 30k, I have a naniwa 12k. I havent had that problem because Im usually only doing 12-15 light laps. I have heard that over that you may have microchips. The film Ive been doing 40 laps on wet paper and on a granite surface plate.

Your statement makes no sense then... Micro-chipping is simply bad honing and is caused by the hands the stone doesn't cause it...

There are posts on this site saying too many laps on a 10k + hone may cause micro chips. I have not had that problem as I have stayed away from too many laps on the naniwa. Fine hones and micro chips search on this site reveals 142 results.

Micro-chipping is simply Bad Honing, and is caused by the hands, the stone isn't at fault.. as you have found by using your Naniwa SS 12k it didn't microchip when you used it correctly.. Same as many who use the Shapton high grits have no issue with micro-chipping..

BTW Lapping flim used incorrectly can cause the same problems, again it is the hands not the medium that causes the issue

Glen,

I just went through this with a Naniwa 12k. Don't know yet, if it was my hand or the stone. But I got really bad chips from the stone. There is a looong thread by me with lots of investigation and pictures. If all these stones look like mine, it is well possible that particles are being torn out of the surface that then cause chips. ( this thread )

Two seperate issues, you have Chips, we are talkng Micro-chipping (Or at least I am)..

Yours looked to be from a bad stone or bad lapping, looks like you finally got it worked out too

I am with Glenn on this.

Film is interesting... it tends to be faster than most hones. I keep some
Woodcraft 15/5/0.3 micron film handy for difficult rescues. The three seem
like big grit jumps but they work well. A little bit of soapy water keeps them
cutting a long time. For the one or two razor rescue this is small money
well spent. A honemaster will want a good pile of water hones.

Once the bevel is set and the razor shaving any flat lapped 10k-16k hone will maintain
the edge. The Na12K is a bargain and might be the only hone a "shaver" needs to
keep a shave ready razor shaving. Shaptons work with little fuss.

The Norton 4k/8k combo is a work horse and plays well with the Na12k ....

For me most micro chipping seems to be related to my heavy hand setting the bevel
with coarse hones especially DMTs. Then insufficient time with middle grit like 4K before
jumping to 8k or a finishing hone. All near 1K hones are not alike.... My Norton 1K
can be improved on a lot by my 2K Green Brick. or a Shapton 1k hone. Film at 15 micron
is a darn fine 1K bevel setter equivalent and new 5 micron film is a lot faster than a Norton 4k.

I might note that for me an edge can be too sharp for shaving. I need to be cautious with 0.3
micron film... it can get me a Feather like too sharp harsh edge. Quality hones in the 10k-16k
seem to differ more in how I use them than the grit. The best value seems to be the NaSS12k
especially when paired with a Norton 4k/8k combo... My Chosera 10K and Shapton are
different but do not seem to shave better or worse, your mileage may differ.

And NO I did not need all these different hones. Some day I will sell -- no, no no... I have HAD too
bad.

Ive recently started using film a month or so ago. I find that the finish with the 1 micron film is extremely sharp but smooth. I do 1200 dmt(well broken in) and 3 micron then 1 micron on granite with wet copy paper under then .5 crox on linen. Great edges and they are consistent. Im only honing since October. Im sure any hone made for razors is capable of putting a superb edge on. Theres a million ways to skin a cat. Ive gotten great edges off a Norton 8k. Then you hear about the 12k, then you buy it. The film was a no brainer, 30 bucks for 3 and 1 micron film. I tried the .3 micron on granite and that was almost like using a shavette.

Glen,

sorry, my bad. Thought those were quite micro and simply thought it's one term.

Yes, got one ready, thanks. I'm still not confident, though. I might return it and see with another one, if it has been this single stone or, if it is the way they are made and extra caution needs to be taken.
