How to create alloy banding on purpose

[Levi Prince]

Hello all, a while back I made a knife with 52100 bearing steel and I got some pretty cool looking banding (which I know is supposed to not be good). BUT I have a project where I'll need several decorative overlays that I would like to make a little more visually appealing than just plain steel. I dont want something as striking as damascus but I saw the old picture of that knife I did and I thought it would do just the trick. I've heard kevin cashen supposedly has a post somehwere explaining how to do this but I havent found it.  So can anyone tell me how to succesfully recreate this banding pattern in my steel? Is it entirely to do with the heat treat and how the carbides group or do you have to get lucky with your piece of steel?
