For those of you who don’t know, the razors with the third pin were the upgraded models. Kinda like buying a new car that has 20 inch rims thrown into the mix.
The blade still has the original acid etch. The pile side of the blade has two very small areas of imperfection from indents of past oxidation that prevent me from selling this razor for an additional $50. They are both less than 1.5mm in diameter and are about .15mm in depth.
