I decided to try getting a Patina on my Gayle Bradley. I've been using Tuf-Glide on it since I got it. I used gun solvent all over the blade and tang. Then I used mustard trying to get a patina and was successful. It has a very consistant patina on the blade. It's a little obvious if you are used to looking at the GB. You can really see it in outside light. The contrast between the blade and the bevel makes it noticable. The bevel is very shiny. It looks good to me. I like the blade a little less shiny but not black on the GB. I may try for a darker patina later but maybe not. After I was done I reapplied Tuf-Glide. Anyway I wanted to let anyone know how to remove Tuf-Glide in case someone doesn't know how. It seemed to work very well. I put mustard on the blade until it dried then washed it off and repeated 3 times. I read somewhere that after the mustard dries it's patina forming ability is gone so repeating until the desired effect is how to use mustard. I guess that is right. I'll try to get a picture but the camera I have is not the best quality.
