I have been working on this knife for a couple of days, filing down the bolster and thinning the blade. The next issue is how to get an even finish. I’m not looking to polish it in full, I am trying to keep the patina as best I can but I did have to work on chamfering off the shoulders of my first thinning attempt to get something approximating a convex grind. I worked up from 320 to SG1000 and have gone no further for now. The problem is I have an uneven polish creating a rippled finish. see video. How do I move from here?
