Mujingfang C-nat (C12k?)

I'm curious about a stone I found on Ebay. It's not a one-time thing or an auction. A wood-working store is selling three types of natural Chinese finishing stone (three sizes that is) which seem rather cheap if the purported grit rating gives any indication of their performance. I'm curious if these are c12k's or something different as I've never seen them boxed/branded, and if so whether that might indicate more reliable performance/quality control.

It mentions being cut from sedimentary rock in a quarry on the box

That is funny 13k :rofl2:

Reminds me of Spinaltap,,, "These go to 11"

Spinal Tap - "These go to eleven...." - YouTube



BTW there are some on e-bay that claim to be 15k too, so they go to "12" on Spinaltap Bahahahaha


Edit: Here is some more info on the actual variations in some of the PHIG's (Peoples Hone of Indeterminate Grit)

My old Galaxy 500 said 120mph, if I remember correct, never would go past 105mph without the hood shaking & it got me caught by the FEDs on the Blue Ridge,,,bad day that was,,,:(,,,you just can't trust the numbers,,,,

Thanks for the info. Been reading through it for a while and still going. There's a lot to process here. Sounds like these hones are fairly well liked by those who get a good one and don't mind investing extra time. It's nice to see one in a box as well. Until now I've only ever seen them being sold by razor vendors and the like.

I don't think anyone really takes it seriously.

Hi,

I'm not sure they are the same stone. I bought one here in Shanghai and I compared my box to a Chinese 12k which someone bought from Woodcraft. The packagaing is very, very similar, but the Woodcraft one had 广西（Guangxi) written in red, and mine instead has 木井方（Mujingfang). Also, my one was quite unflat and took under a minute to lap on 150 grit SiC on glass. From what I've heard the famous Chinese 12k is very hard to lap.

Just checked your link, yours looks exactly the same as mine, pretty sure it's the same one. Unfortunately I haven't used mine so can't offer any advice.

They are stones from the same region in "Guangxi", a province in China,,,,,,,,,,Mujingfang is the name of a company, that is named after a specific type of wood plane famous in China. That same company "Mujingfang" sold C12K's for honing their planes & chisels.

150 grit lapping is pretty course for a stone above 10k like most PHIG's/C12K's thus you got a fast lap. I used a DMT 325 & lapped mine in under 5 minutes. They are hard & slow as the links describe.

Thanks Hirlau,

I bought mine after checking with Mujingfang that the dealer was legitimate. I was suspicious as it only cost 40 RMB, roughly about 7 dollars!

I'll smooth out the surface with some finer sandpaper and have a try.

Your welcome,,, I bet the average price of a PHIG is $7.00 in Shanghi ,da*ned if they didn't mark up the price 400% & ship them to the U.S. :shrug:

Try prepping it like a hard ark. Get it as smooth and flat as possible with loose grit and Silicon Oxide Wet & Dry. Once flat it goes quickly.

Then put hard flat steel to it, Plane blades or carbon steel knives or any kitchen knife at least 3-4 knives about 100 laps each with lots of pressure.

The goal is to burnish the stone surface. It will be a slower cutter, but it is supposed to be a finisher/polisher not an aggressive cutter.

I like old, hard carbon steel knives for this. A side benefit is you will have at least one, sharp knife.

2-3 drops of Smith’s honing oil on a wet stone will get the most out of the stone whatever the grit.
