You mean remove the crenelations themselves? Or just soften them?
Remember, titanium is pretty strong stuff. It may take a number of dremel wheels to do what you are thinking. Do you have any photos you can show of your existing bezel?
Thanks guys for the input. I ended up sanding the sharp edges on a sandpaper with a medium grit and refine with an eraser block. The result is subtle, but I achieved what I wanted. Cheers!
