Thread: Re-visting the Chinese Hone

I have translucent and black and both are about the same and in my opinion (totally subjective) the edges are much smoother than my guangxi edges (which are excellent in and of themselves). I wouldn't go buy a phig right away. Maybe down the road to compare at some point but a well prepared arkansas black surgical is tough to beat.
What a curse be a dull razor; what a prideful comfort a sharp one

Thanked: 19Ok, thanks for the clear info. Slurry stones are available here, will probably have some questions about those a little down the road...
This may be a silly question but... what do you use for your completely flat surface? (and do you use water/running water; and how do you fix the sandpaper to the surface?)

Thanked: 3215Yes, you will need to lap it. They are very hard and you may have better luck with loose silicone powder,
GotGrit.com has all you need, you don’t need much, a tablespoon or two of each grit, starting at 80 to get flat and switch to Wet & Dry after, 500 grit. 80,120,220,320,500 is a good progression, (about $8.50), then wet & dry. Hard stones can strip the Diamonds from a Diamond plate,
Mark a grid on the stone with a Sharpie and sprinkle a tablespoon on a wet steel cookie sheet, (dollar store) and lay on flat cement, use your bodyweight. Once flat it will go quickly. Wet cookie sheet works well for wet & dry also,
The Chinese hones benefit from a fine finish, I go to 1k and burnish with hard flat carbon steel, for razor use, like an Ark, 2-300 laps.
Once lapped and burnished, you do not want to re-lap, like a synthetic. It may cut slower, but will give a finer finish.

Thanked: 433My best Cnat came from the Ebay seller in Poland and is very different from the ones from Woodcraft, it's more like an Arkansas black, it's VERY hard and smooth and reflective like glass. I get great edges by using three series of 20 1/2 xstrokes, some circles and 50-70 regular xstroke all with very little pressure

Thanked: 19Thanks for the info. I'll look into the grits; what is wet & dry? Is that different than the 500 grit?
Honestly, I don't know where I could find flat cement around here... my balcony is tiled with about one square foot tiles and fairly flat, would that work? Does that flat surface need to be perfectly flat (i.e. lapped hone flat) or just flat in the general sense? Any other recommendations?
"go to 1k and burnish with hard flat carbon steel, for razor use, like an Ark, 2-300 laps." What does this mean? A 1k grit against the stone and then rub it with steel? Is this a different method of lapping from the progression of grits mentioned?
"Once lapped and burnished, you do not want to re-lap, like a synthetic. It may cut slower, but will give a finer finish." Does this mean that I won't need to lap the guangxi again, period?
Thanks again everyone.

Grit is the number of particles per square inch. On natural stones, the number does not make sense in many ways, that's why most of us stopped calling it the "C12k"
You'd better start with sandpaper sheet progression, and don't tell me you don't have these, because I buy mine from China. Loose grit is more advanced stuff.
If you are looking for a flat surface, try your table, your kitchen bench... anything big enough that looks flat, and when you place a ruler on it, you can't see between them. or if you drop some water to the one side of the ruler it won't pass to the other, parallel to the ruler anyway. Place the sandpaper on it and start rubbing the stone on the sandpaper until the stone has a uniform finish. Then move to the next grade.
You don't have to use the sandpaper always wet. Dry works as well, just try not to inhale too much of the dust. When you finish, with each grade, and especially when you've finished from your finest grade of sandpaper, wash the stone thoroughly, rub it with your hand, then rinse it again, you don't want any loose particles from the sandpaper to get stuck in the stone.
As for burnishing the surface, that's Arkansas fine stones stuff. It has nothing to do with the Chinese stone, and honestly, after the 400 grit sandpaper, you can start using it, and you'll have the same results, just less drag, compared to a mirror finished surface.
And, you might need to relap your stone. Every now and then, place a ruler on the stone's surface and see if they both are touching everywhere. If a curvature starts to appear on the stone, you'll need to lap it again with the sandpaper.
Also, get a big stone, it will probably be easier for you to learn the "art" of honing. something like 20x7.5cm stone, or even bigger.

Thanked: 19So just to give an update, I got the phig (the larger one, as recommended--it is gray with a light grain, like the second hone in the picture a few pages back). Lapped it on 220, then 600, then 1000 grit sandpaper with a little bit of water; didn't spend too long, I'd say 20 to 30 minutes total. When I looked at it at a steep angle with a light it had a mirror-like surface, so I decided to try refreshing the razor. I did 20 passes with my razor on the stone and was able to feel a difference in sharpness with my thumb (before, when I passed a moist thumb across the blade it felt slick, after 20 passes I felt a sort of vibrating and it made a sound something like the sound it makes when shaving *note: the razor is full hollow ground). So I decided to strop it as normal on clean leather and shave with it. MUCH less pulling than the previous shave, though still a very little bit. After one pass my skin felt totally smooth when I rubbed it with the grain, but still a little prickly when I rubbed against the grain (and I'm still not getting as close of a shave under my chin and throat as I am across my face).
Anyway, thanks for the help everyone. It seems I'm on the right track and with some practice and playing around should be able to keep the razor in good shape.
One more small question, I think I had read that it takes a few shaves after a hone (and refresh?) to start getting the best results. Should I give the razor a couple more shaves and see if it improves, or should I try a few more passes on the phig? I am still working on my shaving technique... but I've shaved enough that I'm pretty sure the result today was about the razor, and not me (mostly).Last edited by ffourteen; 09-29-2015 at 11:45 AM.
