O1 is the closes to black that I have found 1084 is close and 1080 is close to the 1084 that I have used.

Just be sure to heat treat for the O1, it requires a soak at temp.


Here is one I just did in O1 and 8670M, the 8670M shows more gray than 15N20.

O-1 will get plenty dark due to the Mn in it. However, from a heat treatment perspective, it may not be the best match. O-1 also takes a little more care in forging as it will go red short and crumble if worked too hot.

If you want good contrast, easy working characteristics, and a good match for heat treatment, I'd stick with the 1080/1084 (Aldo's 1084 is fantastic with a higher Mn content so it etches darker, and touch of V to help inhibit grain growth).
