Anti-corrosion green liquid/Japanese craftsmen.

[Odissea/1978]

Hi, today I polished my first Japanese knife and I was able to appreciate after an hour of work that it actually rusts while it is being worked can anyone tell me what is the green liquid that you see in the videos of Japanese craftsmen? I know it's an anti-rust liquid but I don't know exactly which one.

Thanks!

I'll try an anticorrosive coolant, it's the simplest thing to find.

Try a little baking soda in your water.

Might I propose a different anti-corrosion inhibitor? It's called edci formula. It's not the Japanese one you are searching for, but it's what I use. Being a micro-crystalline wax, it leaves no residue and it's also been certified food safe.

Thanks for your suggestion, can you tell me more? is it ready? should it be diluted in water? I'm grinding the knife at 120 grit on the stone, the process will certainly be long, it allows me to understand how to proceed with the geometry and therefore without a doubt I need an anticorrosive.

It's ready to use as is. Don't dilute it. Spray it on, rub it in with tissue paper, wipe it off and it's good to go.

I'll take a look, Thanks!

That lime-green liquid is Duraron(ジュラロン) C line.
It's undiluted alkaline corrosion inhibitor. Very hard to buy it outside of Japan.

EDCi Formula and cutting fluid are not suitable for sharpening on stones.

You can mimic some of the properties of Duradon C.
A slightly alkaline environment is an easy way to prevent corrosion.
You can dissolve a small amount of baking soda, washing soda or a tiny amount of lye (sodium hydroxide) in water.

Be careful! Small amount! Alkaline water can irritate the skin.

Slightly alkaline water is fine for vitrified or resin-bonded stones. Don't use it with magnesium bonded splash-and-go stones.

Rv coolant is what I used...non toxic and easily found.

+1. Never failed me even thinning for hours.

It's Chartreuse - this must be why I can't find any anymore. Finally the secret to Japanese knives is revealed - French liqueur!

Kidding aside, washing soda is my vote for this.

Thanks for your suggestions. I already tried baking soda,the result is a little bit better ,"less rusty" while working, I'll not trying anymore sodium hydroxide I had a terribile experience with it when I was younger, my skin is still "burn" from using it, so for the moment I prefer not to risk. I'm using Corundum stone for my progression; I notice that for the lower grit,120 in this case , a dry Corundum wheel will be suitable for grinding shinogi, I find this work on a bench stone really hard so I need to check others possible options; if you are Europe based I suggest you Zische.de Corundum stones, price/ratio excellent for this kind of polishing/grinding work with cladded knife. Any suggestion on grindind on the low grit is welcome,maybe Ot from my thread but....

Can I just use mountain Dew or Monster energy?

Here is a thread talking about polishing, anti corrosion fluids, and related. Read to the end as the poster changed methods. Ultimately used dilute powdered tide laundry detergent as anti-corrosion sharpening fluid.
