Can you clean a handle?

Cleaning the handle is easy. You could do it by hand - it will take a long time, but it isn't bad idea at all. Such way gives better accuracy.

First, Get to Know Your Knife

Supplies For Restoring a Pocket Knife

Wet/dry sandpaper. While there are multiple methods you can use to restore a pocket knife, the one that worked best for me used wet/dry sandpaper dipped in Hoppes No. 9 gun cleaner/solvent. Using regular sandpaper could cause some abrasion from the friction, but by using a wet/dry variety with a cleaner, you’re protecting against that.

1. Give the knife a good wipedown

The first thing you’ll want to do is wipe the knife down with a wet paper towel, including the space between the scales (the scales are just the outer pieces of the knife handle — between them is where the blade lies). This will help you know what might just be loose dust/dirt, versus rust and grime that needs some elbow grease to remove.

2. Spray with penetrating oil

Next you’ll spray the knife with penetrating oil, particularly at the blade joints. Most vintage knives will have build up there, and will therefore be a little creaky on opening and closing the knife. This is a pretty easy fix with penetrating oil.

3. Dip sandpaper in Hoppes No. 9, and go to work on the blade

I started with 320-grit wet/dry sandpaper, dipped a small piece in the Hoppes No. 9 (which I had poured into a small dish), and went to work rubbing the blade. This cleared the majority of the grime after a few minutes. Do know it takes some elbow grease and real scrubbing to get it all. Then, I switched to 400-grit, and scrubbed again.

4. Using a brass brush, clean the hinge and the finer grooves

Next, you’ll use the brass brush to get into some of those harder-to-reach places. I dipped the brush in the Hoppes No. 9, and scrubbed the hinges again, as well as between the scales. This gets some of the finer rust and grimey particles.

5. Wipe away all the oil with a cloth

After all this cleaning and scrubbing, the knife will be oily from both the penetrating oil and the gun solvent. Using a cloth, wipe away the oil.
