I tried to force patina on my sod buster... Bad idea. I used apple cider vinegar. I left it on to long and now I have some rust spots.

:O(

Thanks

Silver or chrome polish works well too. I like the scotch brite satin finish too.
 
Renaissance wax makes a product called Pre-Lim. I have used it before on some of my lower cost users that were beat up bad(some rust, patina,etc).. Works Great. Just let it sit for 3-4 minutes and buff off with a cotton ball. It comes right off and does not leave any scratch marks whatsoever. I'm tempted to use it on some older collection knives that I have that have some patina on the brass, but want to keep them all original. Art Aquisitions on Ebay carries it and are very professional. Although I'm not sure if I can give out names like that. Good Luck
 
Are you going to try it again? There are different kinds of patinas. I "buffed" out some rust on my BRK Golok, but then used white vinegar and mustard then oil. The patina is cool and now I can't tell where the rust was, and it won't rust any more. Well, not so easily.
 
Thanks for all your advice. I think I'll go with the scotch bright because I think the other option would be more expensive and harder to find. Do I buy the kind just used for dishes or do I need to go to a hardware store? Should I go along the blade length or up and down?

Thanks again

Hey I bought a regular scotch brite green scrub pad. Now I have alot of little scratches on the blade. Do I leave them on there or can I make them go away? I'd like for them to go away.
 
if you pinch your blade in your pad and make straight strokes from the ricasso to the tip you'll get a nice handrubbed like finish on your blade.
 
Scotchbrite is like sandpaper in a way. There are different degrees of "grit" from heavy, like green to a lighter grit like grey or brown.
 
I started off with the green. I know of members here that have taken an old knife and made it look new again. Do I switch over to wet/dry sandpaper? What grids should I use to take out the scratches?
 
Why would you have used the scotchbrite anyways? Always try to stay away from anything that will leave marks on a blade or handle. Good Luck,
 
Now that you've used the scotchbright pad :rolleyes:
You have to straighten out the scratch pattern.
I'd clamp the pad on a board, soak it with some WD40 and stroke the knife blade across it in one direction only.
Doing the whole blade at a time.
I would do a large FB from guard to tip.
Pocket knife could be either spine to edge or pivot to tip.
ONE DIRECTION ONLY.
Once all the scratches look uniform you can either call it done or start using wet dry sandpaper.
Again, as above, in one direction only. Don't move up a grit till all the scratches from the previous grit are gone.
Try 800 after the scotch bright... if it doesn't remove the marks go down to 600. The work up to 800 or 1000. If you want closer to a mirror then 1500 and 2000.

Go slow, take your time and be careful.
You will probably have to sharpen your knife from scratch as well.
That green pad will play heck with your edge.

Hope that helps.
