It's like Hollywood magic. You can make a terrible edge look great with the right lighting and angle.

What I learned long ago is a quality 10x loupe or hand lens with great eye relief is all you will ever need to maintain your razors.

Any more than that and it becomes like a guy with two watches. He's never sure of the correct time. I have a Nikon Stereoscope I bought back in the 70s but I stopped using it for razors years ago.
