Very interesting pattern for sure. Have done similar with cable that was questionable and some masonry saw blade then used for outside layers of a 1095 core on a large San Mai blade. Lot of work for a small knife.
It WAS a lot of work for sure. My small group of people and I have a good bit of experience with this cable as one of our guys works on a yard where he gets it for free. It hardens up and skates a file. The rust spots are all on the surface as far as I was able to tell, I DID examine it thoroughly for cold shuts. The one thing I didn't do was polish it back to shiny on the 15n20 before dropping it in the oil. It went straight from the ferric to Windex to the oil soak. I plan on trying this again, next time I'll be a lot more thorough with the cleaning between etches.

If I built issues into it I'm pretty sure a 9 year old using it with appropriate supervision will find them.
