i saw this awesome looking acid etched finish on a knife somewhere on here... it was acid etched but it had shiny splatter spots all over it, like someone randomly splatter some acid resistant material on it before dipping. just curious what liquid material you would use to splatter on, that would dry and protect that area of the blade from acid?
 
I know you can use nail polish for a resistant but I also have heard of using a sharpie and coloring it in twice. Just try your etch on a scrap peice to see how it works before putting your blade in.
 
Paint/nail polish, candle wax, hot glue, etc. a lot of different things would work.

If you look at some of Michael Raders knives he has done a mustard patina on the blade.
Gives a cool random spotted look.

that's cool, but i really have a thing for the finish that looks like you dipped a paintbrush in paint and just slashed it across a wall (without actually touchin it), with a bunch of long splatter lines

polish and wax were the first thoughts going thru my head. just have to figure out the flinging action
 
Also Testor's model airplane paint can be used. It may last longer in the echant than wax or nail polish, which would give you a sharper contrast between etched and non-etched.
 
I've always imagined hot glue guns were used on blades etched like that. Drip a few small blobs in different areas then let the glue kinda string down (the higher you hold the gun above the blade, the thinner the "strings" will be) from the gun as you move it around randomly (slower or faster for different looks). Might take a couple tries to get the look you want. Just my 2 pennies :D

Here is one I did with spray paint and ferric chloride. I soaked a rag in spray paint and then just slung it across the blade to splatter on as a resist. Then dipped in and out of FC for about 3 minutes. Cleaned it off with mineral spirits and neutralized with ammonia. Then I stone washed the blade in a tumbler for about 20 minutes.

 
You can also splatter paint onto a knife by holding a popsicle stick at an upward angle in front of the spray nozzle. The paint gathers on the popsicle stick and the force of the spraying makes it splatter off onto your knife. It's an old airbrushing trick I learned in high school, but it works with rattle can paint too. Warning, it will splatter everywhere in front of the popsicle stick, so make sure you're not aimed at anything you don't want painted. Hold it closer to your knife for larger drops and further away for smaller ones.
 
It would be the same as any other forced patina or acid etching. Scratchable, rust resistant where it is etched and not where it isn't, carbon steel can still patina over top of it.
