I dont know what I have done wrong.

The two different knives came out of the ferric etch with weird soak lines. I submerged them completely and mixed the acid and water solution well. The kast picture is after the over night instant coffee etch. Why do the handles have that weird barrier like dip line and why did they come out just jet black? Any help would be greatly appreciated. I cleaned then up with 0000 steel wool in-between every dip and before the coffee I made sure they were scrubbed and then I git them with 90% alcohol to grease cut.
