A couple weeks ago, I picked up a small lot of razors. Someone had posted a fuzzy picture of their old razors on a table, asked for a cheap price and a couple of them looked interesting. one of them was a Puma Special 68 (or 89, depending on how you read it) I oil it, sanded it with some wet/dry sandpaper (400 grit, then 1000 then 2000) and then polished it with some Mother's Mag Wheel cleaner. I then sharpened it on a 4000, then 8000 then 12000 stone and stropped with Chromium Oxyde then on plain leather. It shaves great.
I'm having challenges getting rid of the black pitting on the blade. I've been wiping Ballistol Universal Oil on it in the hop that the black-rust in the pitting will softened and will remove during a future sanding. I'm reluctant to try rust removers, since I assume they may be acidic but reviews of Birchwood Casey Blue and Rust Remover looks promising.
Does anyone have a recommendation? Should I simply move down to a 400 grit paper and sand harder?
Any input would be appreciated. Below are pics of what I started with and the improvement so far.
