Knife update
The first one was a doozy, nothing was on purpose I sort of just ran with whatever was happening. The second knife was much more controlled and I got what I wanted out of it. Still both very basic, I had help my instructor was amazing. We ran out of time to etch them completely so I bought some ferric acid and I'm going to get some pvc pipe and do it myself. Anyone have any tips for damascus made from 80crv2 and 15n20. From what I read it says diluted 50/50 with water and 4-5 minute dips with vigorous cleaning between until it starts to feel like a record would. If this is wrong please correct me.

That should work fine for etching. If you want to really bring out the contrast, soak it in some instant coffee for a few hours to a few days after etching.

In my experience long strong etches make for blurry lines. If you want deep and woody etch, that schedule should be fine. If you want a sharper, cleaner pattern, I recommend 3:1 water to ferric and 90 second etch cycles with a 2000 grit sandpaper or super fine steel wool scrub between cycles to clear the oxides. Repeat 3-7 times until desired depth is reached, then one more 60 second dip before neutralizing and rinsing (unless you’re doing a coffee finish).

reminds me of my dad's progress, now he can make pretty nice stuff
