Damascus contrast question

[BKM013]

I’m relatively new to blade smithing, but I finally graduated to Damascus. My first billet and subsequent blade turned out fairly well. I used 1095 and 15N20, but I didn’t get enough contrast to suit me. Perhaps I’m missing something, I’m not sure. I learned all I know thru trial and error. To remedy this I’m switching to 1084. I have nickel 201 annealed sheets that I’m planning on using in between each layer of 1084 and 15N20, will this help with contrast or be more trouble than it’s worth?
Also, any thoughts on the perfect grind for a Damascus? Maybe 600 grit followed by 1500 grit for the top of the minuscule ridges?
Any advice is greatly appreciated, thanks.

1095 and 15n20 should contrast fine. What's your etching/finishing process?

I'd start with 15 minute cycles in 1:4 Ferric Chloride till you get the look you want, then perhaps a coffee etch. Finish to 600 at least. If you do decide to polish the tops like you suggest, use 2000-2500 grit and real light pressure.

Perhaps my etch is a problem I didn’t even think of, I’ve been soaking in straight ferric chloride for 10-15 seconds then neutralizing immediately. This leaves the 1095 a medium to dark grey instead of the blackish look I’m going for. The 15N20 ends up a light grey thus the high grit finish in an attempt to lighten it. Thank you, I’ll try your advice out.

Diluted ferric and longer soaks will definitely be an improvement.
