Yesterday I shaved with my Feather AS-D1, where both the sides shave identically. This morning, I opted for my black handle Gillette Super Adjustable. It was quite noticeable that each side shaved differently, with one side being distinctly more aggressive than the other. I was using an identical Feather Platinum blade in both razors. What do folks think: Clever feature or manufacturing tolerances? My guess would be manufacturing tolerances in what was a relatively inexpensive mass produced product in period, although I bought mine as NOS long after production had ceased, when my local privately owned pharmacy was sold to a chain. One of the other razors I use regularly, one of my three Stahly Live Blade clockwork vibrating razors, are between the Feather and the Gillette, with each side shaving fractionally differently from the other but nearer to the Feather. One of my Stahlys is an early type, all heavy chromed brass. The other two are late model prototypes with brushed stainless steel heads and black anodised aluminium bodies, containing the clockwork mechanism. I believe this model never went into series production.
