I have a knife that I want to take some of the patina off the edge with a rust eraser, but I'm worried it will take some of the clad finish off with it. Looking for some insight on this subject matter.

The edge is rarely clad, and if it were, you wouldn't be erasing up the blade road.

Why the eraser? Why not just an abrasive like Bon Ami or Barkeepers Friend?

The clad starts about 3 to 4 mm from the edge. I haven't used anything else but rust erasers thus far on patina for my knives. The only knife I typically use it on is my deba, but I have a Japanese chef knife that I don't like the look of the patina on. It's blue steel #2.

Simichrome is a great polish but it's toxic and slightly abrasive. I wouldn't use it on food use items. Bar Keepers friend is good for patina removal and very much dilutes to nothing after rinsing off.

Try some bar keepers friend and then force a patina with a good starchy potato. It will be less pronounced than mustard.

I use flitz as a polish. It buffs out nice. Then I wash it afterwards.

I use this on my blue #2 kono that I like to keep polished.

How do you use that bar keepers friend? Do you just rub it on and let it sit then rinse off, or is there more to it.

BKF comes in powder or a less abrasive liquid. I use either one with a cork to scrub the blade surface, then rinse. Some say to neutralize the oxalic acid in BKF with baking soda, but I've not found it necessary if you rinse well.

antoher vote for barkeeper's friend. We use it at the office to clean up knives that are sent in for sharpening and repair. It's quick and easy.

Baking soda and a wine cork.
