i know bad on me for letting it rust, i cut a orange while out and about and by the next day it was too late. i sent it into kershaw, when i got it returned to me it looked like they hit it on a buffing wheel. the spots are still there and now the blade looks lighter. any suggestions for fixing the finish look?
 
sell it to me, that way it will no longer be a problem you have to deal with....
 
Give it to me and I'll use it lol... Soak it in WD40 for a day and wipe off with a rag.. It won't ever be like new but it will help with preventing future rust.. And the Damascus will get dark again offer time.
 
Rub the blade with oil and 0000 steel wool to get rid of the rust. You'll probably want to disassemble the knife first to keep bits of steel wool from getting into it.

If you're feeling adventurous you could try re-etching the blade. I make no guarantees on results and you'll almost certainly void your warranty. Google "etching damascus," you'll get plenty of results to comb through.
 
You can't just flitz Damascus it will polish it and take the darkness away..then it would look like a Shun where you just see lines... And read before posting, the rust was taken away he wants to know how to get it nice and dark again....like I said it will slowly get darker with age
 
Use PCB etchant from Radio Shack. Dilute to I think 6 to 1. Pull the blade out, protect the tang where you want to keep it smooth so it opens nicely, dip for 15 minutes or so, rinse. You can redip to get a bit darker but don't overdue it or there won't be any contrast. Use a bit of sandpaper on a block so you have a nice straight stroke and hit the high spots stroking from the spine toward the edge. Hit the edge with a fine stone to sharpen.

Yes, I have revived a knife this way and not just talking. Worked on a Skyline. I diluted the etchant with vinegar as well as water but I don't think it made any difference. I may be wrong on my proportion and maybe diluted it
less. It is easier to redip for longer than go too far and have to have it rebuffed and start over.

I've read muriatic acid for cleaning bricks works as well and may be easier to find at a hardware store. I know lots of guys use it to acid etch blades before stonewashing to give them that industrial look. I think ferric chloride PCB etchant works better on some steels. Jonnymac44 may pop in and comment on the differences. I know he has experience using both acids on a variety of steels but don't know if he has done damascus or worked with the Alabama blend of damascus Kershaw uses and I don't remember offhand what steels are in it. I know it has been diacussed and a quick search should find it if Chester22 doesn't know offhand and comments immediately.
 
This is the layers Alabama Damascus uses

(4) layers 5160 (3) layers 203E, (3) layers 52100, (3) layers 15N20 folded 5 times for 416 damascus layers

I'll be doing a Damascus skyline this weekend, I'll take lots of pictures and make notes of times and solution concentrations. It's my first shot at it but I've done a fair bit of research so I think I'm OK
 
Looks like I did half water half vinegar from some info on Knifeforums. Since vinegar is acetic acid already diluted to something like 90% water I think that is where I got the 6 to 1 ratio.
