Removing rust

I see some light rust developing on my Cold Steel Carbon V LTC Kukri. Normally I would take some steel wool to the blade very gently but this knife has a black epoxy powder coating that I don't want to remove if at all possible...any suggestions?
 
Confused here...and it's probably a dumb question but here goes:
The powder coating is on the blade right? (the word "epoxy" has me wondering)
If its not on the blade I'd just masking tape it.
If it is on the blade I may still try it. I use some REEAAL fine steel wool (can't remember how many 0s) to my blued guns all the time if they've got some surface rust. While I'm sure it's not exactly "good" for the blueing I've put some pretty good elbow grease into the job before on beat-around guns and at the end of the day couldn't see any harm.

Birchwood Casey's SHEATH product helps the process noticeable as well...but I don't know how that stuff will effect powder coating.

Yes the powder coating is on the blade. I might try the tape idea as it seems like it could be more gentle on the finish. Thanks for your help!
 
I've had good results using Hoppe's gun oil and a rag. Really works great, and leaves a slight film on powder coating (on my kabar, for example).
 
Once you get the rust off the best product in the world is EEZOX KNIFE CARE. They make it for guns too, but just started making it for knives. I have used everything in the book over the last 20 years and you can't beat this stuff. Tuff cloth or tuff glide is much weaker than eezox and works half as well. Good luck.
 
(Probably gonna horrify those who care about the appearance of a knife vs. those who actually carry a knife to cut things with) I use a phosphoric acid solution occasionally sold at Lowes and Home Depot that chemically reacts with rust stops the rust process and turns it black. Most of my carbon steel blades are treated with the stuff, then oiled and occasionally wiped.
 
I LOVE a product by the name of "Tri-flon". Have used it on guns for many years, (blackpowder & modern), and I've always had excellent results. Will break down the rust & leave a film of teflon behind. A great product, and will not harm the knife in any way. MAY darken wood, not really meant for that.
 
Phosphoric acid is not recommended for use on springs. I would think knife blades fall into the same category.
 
OK, my 2 cents....I use Never-Dull unless the rust has already formed pits. Never-Dull is in a black can sold in hardware stores, will clean brass, silver, steel, with less abrasive action than 000000 steel wool wet with oil. Actually it's a large cotton ball treated with solvents and oils....you simply pinch off a piece and use it.
 
I've got a Boker in carbon steel that rusts as you look at it...or it seems that way:)
It's got an etched blade and I didn't want to damage the etch so I tried this and it worked a treat.
Get a kitchen towel and put a little vinegar on it then cover the wet area with table salt. Rub this over the rusted area of the blade, then rinse off. Done.
 
Yep..sure does. I should have said that.

Usually that's what people want with carbon blades. Patina

I think the knife in question has a dark epoxy coated blade anyway.

I second that, I use SHEATH on guns and knife blades, does wonders! My carbon V arc angel reacts well to some SHEATH and a little rubbing even with a cotton cloth, takes off the surface rust for the most part. Love that stuff.
