I'm trying my hand at acid etching / stonewashing. I made my first attempt on a cheap gas station knife. The blade (mystery steel) originally had a bead-blasted finish. I followed the directions in this video. I didn't have any acetone on hand, so I scrubbed the blade clean with Dawn dish soap and rinsed in hot water. I then submerged the blade in a 1/3 ferric chloride 2/3 water solution for 30 minutes, wiped it off, then gently tumbled it for 5 minutes in a Gatorade bottle filled 1/2 way up with rocks from the backyard, dish soap, and water .
The result was pretty good, the finish came out pretty similar to the factory "blackwash" finish on my ZT 0357BW, except a couple of shades lighter.
For my next project, I would like to mimic the mild stonewashing effect of the Shaman on a Lil' Native in S30V. Does anyone know how to go about that (i.e. how long to submerge the blade in the acid solution, and what kind of media to use for the stonewashing?) With the backyard rocks, the stonewashing produced a lot of longer "scratches" in the finish like lines. The factory Shaman stonewashing has more short dot-like scratches on the blade. Maybe I should use gravel instead of larger rocks and/or tumble it for a shorter period of time?
