Looks good! Yeah, I remember reading that the initial surface prep was one of the reasons people were always unhappy with the results from those "home bluing" kits. I've had some interest in that as I've been reluctantly leaving a lot of my homemade steel stuff unfinished lately. Some attempts at heat treating got me a cool looking dark coat which seemed pretty tough, but it wasn't uniform enough around the part to look intentional. I'd be interested in whatever recipe you arrived at for the peroxide/salt process.It was polished to 1000 grit wet/dry before the peroxide/salt solution.
