A friend gave me a 9" Sog.

The blade is in good shape but had some scratching and very small pits.

What is the best way to clean this up?

I have a belt sander but have not done much with knives on it.

Thanks.
 
You could take some sandpaper and give it a kind of hand rubbed finish. If there is rust or pits in the blade I would recommend Barkeepers Friend or Flitz.
 
Could you post a picture? If it is what I suspect it might be it may be better off the way it is.
 
I will try to get a photo up today.

Sorry for my slow reply, but I had a small emergency right after posting yesterday and was unable to get back.
 
Were it mine, I'd just take some Mother's Mag wheel polish and a couple of rags, and clean it up that way. It won't remove deep scratches or pits, but it will clean it up real nice and make it look a lot better. If the results didn't please you, you could move on to something more aggressive.
 
Here is a photo of the blade:

This blade has been thoroughly cleaned with my best motorcycle finish cleaner.

You can see the scratches all along it. The stained area to the left of the logo is not actually a pit, but it does not come off even with cleaners and elbow grease.

There are a few other stains like that one and scratches from front to back.

Otherwise the blade shines and the edge, handle, and sheath are fine. The knife is usable, but I am hoping to clean it up.

Thanks for any ideas.
 
what a great friend you have!
it's a classic tigershark.
removal of fine scratches?!
with an abrasive, working by hand is best, but it sure takes some doing.
i like flitz as a final finishing agent.
 
Thanks,GIRLYmann:

What kind/grit abrasive would be best?

I have had this knife for a while and my friend is likely to visit soon, so I want to show him that he gave it to the right person.

I am hoping for a pristine surface or as close as I can get.

I have a belt sander and a leather belt but not much experience with knives and I do not want to do something that will make it worse.
 
Do not use a belt sander.

You will make it much worse.

The only choice you have is fine sand paper and oil.

Rub the stain from top to bottom........but realize the rest of the blade needs the same treatment.........top to bottom to mimick the factory brushed look.

If you had a scotch brite 3 m deburr wheel you could make short work of this but do not get near the SOG logo.

Elbow grease and top to bottom sanding should work fine.........it may take a while.

Thanks for your help. And I am glad I held off on the belt sander.

On another post, I found this advice, which seems good and is similar to what you have said:

You'll need 240,320,400,and 600 sandpaper.I would remove the blade but its not absolutely necessary. Clamp the blade onto a piece of wood using something between the clamp and blade to keep it from being marred.Make sure the entire blade has wood under it to keep from stabbing yourself.Use a piece of leather or similar firm but flexible material as you backing for the sand paper.I think it should be around 1x2.Personally I would knock the sharpened edge off the blade until your done and then re-sharpen. Beginning with the 240 sand the bevel up and down(spine to edge,edge to spine).Take great care not to sand over where the bevels meet the flat part of the blade.Be sure to sand all parts of the bevels evenly,not just where the scratches are.When you can no longer see the scratches your friend made,look closely at different angles with good lighting,proceed to the 320.With the 320 you will sand left to right(tip to pivot,pivot to tip).Once again take great care to not sand the transition from bevels to flat.When you have removed all the sanding marks from the 240,check carefully,you can switch to the 400.Sand from edge to spine until all the 320 marks are removed taking great care again.At 400 you should have a very nice finish.If you want it shinier go to 600,sand tip to pivot,and then sand spine to edge.Reassemble,sharpen,and your done.

Is there anything like the scotch brite 3 m deburr wheel for a belt or disc sander? Would it work for this knife?

Thanks for your help. After looking around this forum, I want to start making knives...
 
if it's just light surface scratches, don't over do it with sand paper just yet.
try some rubbing compound first.
also that it's best to try it on something of a similar material first.
perhaps an old kitchen knife...
 
Yet another problem with this knife is I do not have anything similar. I am not sure how it will respond.

I have a cleaver that looks the same, but I doubt it is. I may try something on that to see if I get any ideas.

Since the knife is a bit of a classic, I would hate to make it worse.
