Thank you all for the comments on the razor.
I shaved with her last night and wow, super smooth shave, very sharp.
It's the smallest blade I've shaved with and it was a little different, but it made my upper lip much easier, haha.
I used 3M starting with 60 girt, then 120, 320, 400, 600, 800, 1000, 2000, then mass with a gun polishing cloth.
