Guys, a few of my carbon steel blades have quite a patina.

Some blades develop an attractive patina over time.

Others - well, not as attractive.
So I was thinking of using some cold blue on these.

Any recommendations on a specific brand of cold blue,
and where to buy it?

Thanks,

PS - NONE of the knives are Cold Steel. I see now in the thread title
it could look like Cold Steel. But I only meant carbon steel.
 
Forget the cold blue , that never works well for large areas. Normally makers and users try ferric chloride, vinegar [acetic acid] lemon juice [citric acid] and even ,IIRC, hydrogen peroxide. experiment a bit. You might do a search in the makers section on "patina".

Thanks, I'll check into it.

Appreciate the help.
 
I've used "Gunslick Brand" Gun Blue, Made in USA on a 1050 Cold Steel tomahawk and a carbon steel bayonet. It was purchased from Canadian Tire, a hardware oriented department store. But I'm sure Walmart has similar products in the hunting section. It turned out better on the tomahawk, which I suspect has to do with the surface quality of the steel (the tomahawk was rougher from sanding while the bayonet was only wooled over). The hawk doesn't smell anymore, but the bayonet being in a sheath still smells after a year and half.
 
I've been told that a product called "MetalGlo" works well, but I've never used it myself. Anyone have any experience with it?
 
Well, one of my Anza knives had a patina I wasn't too keen on.

I was going to try the vinegar idea, suggested above, and
to prep the blade I worked on it with 0000 steel wool for a while.

Anyway, it looks really good now - just from the steel wool rubdown!

Thought you guys might like to know.
 
brownell's dicropan T4 cold blue (not the hot water kind) and Oxpho blue tend to work well, the dicropan being the easiest to apply, and also leaving a nicer looking finish.
 
i used mustard and really liked the pattern it left. the thickness of the mustard enables you to get various patterns depending on how you apply it as opposed to straight vinegar.
 
I would like more info on the vinegar and mustard also.

I think I'm going to stay away for now from cold blue for now;
been doing some reading about the "side effects"...

Thanks for the info, though.
