Thread: Chinese 12k question (s)

I hear you. It just seemed like everyone was talking about the 12K versus the coticule as a finisher. I am curious about the 12K being used after the coti. I know people say that the escher's can improve on a coticule edge, would a 12K do the same?

Also, Pjrage, what's you progression?

I use bbw/yellow to finish on and refresh /Maintain. I got a nice ch12k of a polish chap on ebay it was about 6x2 aprox. It comes already lapped and only cost 19.00 pounds with delivery. And i have to say honing on the 12kch feels realy good. I did 100 laps after my coti followed by ch.5 on s/s dovo and it was ultra smooth and literal glided. So i took ch12k to another razor and did the same on my dovo prima klang which to be fair shaves exallant and i did'nt notice alot of differance realy so its hard to say because it could of been the ch.5 that added the ultra glide i'm not sure but i no one thing it is a nice hone and a good polisher you never hair any down sides to that hone apart from it is slow 50 to 100 laps what i do and it does'nt take long.

I personally did use the chinese 12k after the coticule a couple times. For me, it was a noticeable improvement.

My progression lately is starting with the dmt 1200, followed by the norton 4k (or bbw with slurry), then the norton 8k (or coticule), then finishing with some combination of eschers/vintage thuringians, nakayama, chromium oxide paste, and the < 0.5 micron red paste karakoup1 sells in the classifieds. I'm still relatively new at honing, so I'm in the process of running tests on all of my hones to see exactly how they perform and finding out exactly what I like best. For what it's worth, I haven't been using the chinese 12k lately, but I'll definitely be getting back to it to run some proper tests with it after I finish playing with my newer hones.

I thought I'd be in that stage as well, but now this is going to be permanent.
Guess I'll give it away.

I had a thought that if they were just slightly different in their scratch pattern, one would tend to cancel out the other. So, I am working at a declining number of strokes on each. The coti I have is significantly faster than the Ch12K

Coti Ch12K
10 30
9 27
8 24
7 21
6 18
5 15
4 12
3 9
2 6
1 6
55 168 total

I am getting some pretty sharp smooth edges. I have examined them under 100x. At the end here I have sizable patches where I see no scratches at all. I am thinking that's good. (sorry can't take pics).

There is no reason I started using these number of passes. I figure you have to start somewhere. I used the WAG principle.

These ongoing discussions about the Chinese 12K are basically enlightening and have been more or less positive in nature - that is to say , the Ch12K is recommended more often than it is not. I'm glad to hear this for two reasons. 1. - I have a Ch12K and 2. - I have received notification today that my Naniwa 12K from SRD is in the mail and will arrive forthwith. All this means that in a very short period of time, I will finally find out once and for all which stone is better.

I am tempted to share my eventual results regarding my findings in a manner consistent with the manner in which a professional consultant might present his findings - that is to say I am tempted to charge the going rate for the information I am about to compile regarding this matter.

On the other hand, my God-fearing nature coupled with my basic love of my fellow man will probably force me to publish my eventual findings right here on the forum just like all the rest of the kind and good-hearted members do on a daily basis. I want to be like the rest of the fellas, caring, sharing pillars of society.

Please standby for my findings. Hopefully at no charge....!!!!

What are your conclusions?

'Recently used the c12k to try to duplicate an experiment posted by the Shapton 30k guys. Some notes, having read the whole thread.

Number of laps: remember The Zowada photos? Remember the number of strokes w/ each stone? (20). The number it takes for me seems determined by the hardness of the steel. The wackers never lose their scratch pattern entirely. Others do & just show a mirror finish. Dovo hcs, Genco fluid steel - about 20+ laps. The Wackers - about 40-60.

I have found that using the stone dry for the last strokes seems to make it a bit more fine and agreeable for most blades (not all).

The shapton guys were working on finishing w/ a micro-bevel by adding a layer or two of tape for final strokes. After doing 20+ strokes without tape, I'd add 2 layers of tape, and do the last (20-40) strokes with the stone dry. I'm pretty pleased with the result.

Side note on other finishers: They all seem to need a bank loan and a phd to use. I wish that weren't the case. 'Would like to try an Escher and Asagi, but I need to be adopted by Golden Sacks to do it.

Some good reading there

If you fellows think that the 12K is a honey of a rock, you should try the 15K PHIG, that rock ROCKS!!
Just got done doing' about 55 total strokes as a finisher and it pop arm hairs like a buzz saw through balsa!
By the way, I just came off the 8k of my Norton before the 15K stone.
I"m still new at this, after over 2 years of doing only my personel razors I think my honing is starting to get some were, ...................I think!?
