    I don't know what Murray uses in his mix.

    It looks like the copper got snagged by the core steel for sure as well as something in the damascus mix too.

    There is a smith up here on the west coast, that actually blends pure copper in his damascus, gives a ribbon effect. More ornamental than practical! But looks cool!

    I did this once kinda by accident, I was using monel 400 which has a significant amout of copper, the copper migrated into the steel, and it made the steel "funky" Don't ask me to be more clear on this, it just felt wrong. I think, but cannot prove that the copper migrated into the boundries of the crystal structure of the steel. I do know that it broke easier than my regular damascus, and it did feel funky when grinding it.

    As far as the copper colored etch, this has happened to me many times, and is usually followed by the sort of reation that follows hitting ones thumb with a hammer. The copper adheres to both types of steel in the damascus and is usually a very thin layer which is not stable. if the knife sees any sort of use the copper coloring will be gone in very short order. Copper is much more reactive than steel.

    I don't get it? Is there copper in the Damascus, or are you adding the copper somehow your self? I.E. how did you do this?

    I always thought those are made by mixing copper and iron, I have seen many on japanese sites.

    Bang my head against a wall, but I don't get it. That copper etched blade looks like someone dipped the blade in a bottle of Pepto-Bismol. That knife would make a great gift for a Mary Kay associate.

    I'm with 99 on this one. Not only do I not understand etching enough to be slightly confused by this thread, but the look also doesn't do it for me. I also have a type of color blindness, so maybe that is it. Anyhow, good luck with the experiment, and I am interested to see how it comes out.

    The process is to add copper to etchant and soak until desired results are obtained then finish blade to the appropriate level. The copper is in the surface of the steel enough that it'll stay put but how it wears is anyone's guess. Normally when this is done it's not on purpose, it's an accident that occurs when etchant gets tainted. Some people do use it for effect on damascus bolsters or endcaps, etc. Normally you don't get the strong coloring effect that this blade took on as it's usually streaks of copper seen only. The copper will patina quickly and turn dark. It's not a look for everyone.
