CLR, Vinegar, Mustard, etc...

I tried the potato method, but I never got a nice even color.

I like to stand my knives up in a shot glass full of plain old white vinegar. I did this with an Opinel No. 7 and a Case CV Mini Trapper. The result was a deep even gray color. The patina seems to protect the blades very well.

Has anybody ever tried to cold blue a knife blade? I don't have any cold blue here, or I would give it a try.

Do you mean the cold blue you paint on and let sit, or do you mean the OLD cold blue(that I have heard is better than hot blueing) where you hang the metal over the solution and let the vapors rise and blue the metal...This is supposed to be the best and longest lasting finish you can get.
 
My coffee induced Case ChromeV blade looks to be a little darker than that khurki pic above and it has a similar buish hue if you look at it right. I'm so impressed with it, I wish I could show you.

Has anyone been able to put a patina on D2?

Here's a shot of one that Ariel did in D2:

The thread he posted it in is located here.

Allin,

I submerge the blade entirely, not just the hot edge.

As for the finish and hamon line, I clean the blade and place it on a container with iron perchloride, and the steel get that way due to the high carbon content of the D2.

Regards,

Ariel

Iron Perchloride.. or Ferric Chloride is the strongest etchant I have seen mentioned. I hear it can be had at Radio Schack, since it is typically used on circuitboards. Coffee and vinegar are not strong enough for D2, apparently this is. Some day I'll have to give it a shot. Good info!
 
Has anyone put a patina on or cold blued S30V? I have a skeletonized knife that I would like to darken.
 
Key to keeping the protective qualities of this kind of surface coating is constant lubrication in the form of a light coating of oil applied every now and then.
 
I jammed one of my GEC into two strawberries, and got it done in an hour. It looks awesome now. I'll have to post up a pic later.
 
I'm not sure I understand why would you want to make something new look old? I got some high carbon blades that look amazing but it just happened naturally with use and when I give it to my son I can say now that's knife has some good years on it! If you just use it, that's about as fool proof way of developing a patina you can get!

A forced patina will provide some level of protection to the steel and yes Esav, I agree. :)
