Support BladeForums! Paid memberships don't see ads! Good Morning BF, I had great success removing scratches and tarnish from the stonewashed blade on my large Sebenza 21. I thought I’d share... On my way to work yesterday, I noticed a weird tarnished patch on my blade. I got to work, tried to remove with alcohol, soap, oil... no effects. I thought, hmmm, maybe some 2000 grit sandpaper would do the trick. It did not remove the tarnish, but it was successful at leaving crazy scratches on the blade. Now feeling very discouraged, I remembered that I had a big chunk of the green bark river compound in my drawer. I put a drop of tuff glide oil on the blade, colored the compound on like it was a big crayon, wiped it around a bit with a q tip, and then wiped it clean. I repeated this 30 second process about 6 more times, and the scratches disappeared, as did the tarnish. The stone wash blade looks perfect. I even flipped the knife over and repeated the process on another known scratch, and it was removed as well. I am not sure how this would work on a blade with satin finish, but I was pretty amazed by its effect on the stone wash. Save the trip to the spa, and give it a shot.
