I have posted some pictures of a few ZT's that I have acid etched and stone washed before but I thought while I worked on one tonight I would take some pics for others who are "ballin' on a budget" and want to give this a go.

Final Objective: Darken Ti scale, Acid etch and stone wash the blade, procure toxic green scale from one of our trusted ZT scale makers.

What you will need: Torx drivers for take down (I stared using wiha drivers about a year ago and will never go to anything else), Acetone or rubbing alcohol, nail polish remover (I had to ask my wife which color she cared the least about), Ferric Chloride or PCB etchant, dental floss, a glass jar that is taller then your blade, lots of paper towls, oxi clean, and a heat resistant dish.

1. Take down the knife without bumping table and knocking all your hardware in the floor. Eh, it wont be the last time.

2. Assemble all ingredients in one location near a sink and a microwave.



3. Fill Jar with etching liquid and place on a paper towel in case of dribble.

4. Clean blade with acetone, and then paint up the pivot area of the blade with fingernail polish. Be sure to encompass the area in which the detent rides on the blade.


5. After the polish dries, loop a strand of dental floss through the pivot eye and slowly dip the blade into the etching liquid. Hold the floss across the top of the jar so that the tip does not touch the bottom of the jar, and screw lid on snugly with the excess hanging out.



6. Mix a scoop full of oxi clean into a dish full of hot water (heated 2 mins. in the microwave on high) and submerge the cleaned ti scale of the knife into the solution.




7. WAIT.........45 mins.


8. Remove the blade from the liquid and clean it off with paper towels. DO NOT WASH IT OFF IN YOUR METAL SINK UNLESS YOU WIFE WANTS AN ETCHED SINK!
Also remove the scale from the oxiclean and wash it off with soap and water.





This morning I headed down to the shop to do the stone washing. On my way, I decided since this would be a personal user, I would do two different washes; one on each side of the blade. I taped up one side with waterproof frog tape, did one side, then taped up the finished side, and washed the other. You will see the difference in the pics.

Here is the tumbler we use at the shop with ceramic medium.



In this first set of pics, the blade was tumbled on High for 6 mins. to achieve a more traditional uniform "pattern" on the right hand side.





On the reverse side of the blade, i tumbled on Low for 3 mins. then Hi for 30 seconds. This gives a more "Nuked" finish to the blade.





Hope this info can be helpful to anyone who wants to give it a go. Feel free to ask any questions.

Nice, and thanks for all the pics of the process. I really like how that turned out.
 
Looks awesome so far. Look forward to the pics of tje fijished product. What did you use to clean the ti before the oxi clean? Been thinking about what to do with the ti on my 550. May try stonewashing at some point.
 
I just lightly rubbed down the ti with acetone before i soaked it. Seems like it takes better that way. I have only done one other 0550 but i think the blade will end up similar to the last go around.

Last attempt:
 
I've been considering sending my gen 2 0550 to be acid etched and stone washed, but it really doesn't seem that difficult. I'm still working on my sharpening skills and I'm not sure I could get the edge back to where I want it after stonewashing. I also don't have a tumbler.
 
Etching is not a big ordeal at all. And there are LOTS of tutorials about stone washing at home in your dryer. I dont know what you're using to sharpen, but it took me less than 10 mins. on my sharpmaker to get back to shaving sharp.
 
Looks awesome! You're right there are a lot of tutorials on acid etching and stone washing but not a lot of info on the ti oxi clean treatment ;)
 
^lol, that was actually something i picked up at a GLOCK shoot from a guy who had a TI light on his gun. It was very dark and I asked him how it got that way. Well....thats how.
 
Wow! Such a great, informative thread. Thanks for all the pics...I'm showing this to my wife right now. Needless to say, she's a little confused haha
 
Really nice. Why do you cover/paint the detent before the blade etch?

I find that it the etchant gets into this area your smoothness will go way down hill, and it seems to mess with how the blade breaks detent.
 
I assume you completely tape up the pivot and detent area before the stone-wash treatment?

Thanks - that's what I wondered. I noticed that when I didn't cover this area and etched a blade. It went away with some polish and time, but I will cover next time the way you did.

For the record - best looking ZT I've seen to date. Really like how it turned out for you.
 
Great step by step of how you did it. Looks great! Might have to try it someday to one of my knives.
