I bought this blade for cheap and it can still shave the hair off my arm. This is my first blade I have purchased with a barbers notch and with see thru bone scales. I started out with a clean and light coat of nearsfoot oil. I left the oil soak on the inside and out by way of a light coat applied with a cotton ball and a q tip for the inside of the scales. After a 30 min soak I buffed the scales of unsoaked residue and let them rest while I polished all the metal surfaces. I got most of the stains out but I’m sure a wheel would be a whole lot better to clean it up. Once fully polished I coated the scales with Ren Wax and polished some more. Here is the end result thus far, im sure I would like to go a little bit more with this restoration but at another time. For now I’m quite impressed so far. I anybody can help me date this blade that would be helpful.
