Today I had my best shave in 53 years and I don't even know the model. I used a new Personna Stainless blade with a light lather from Williams soap. This was my first open comb shave and it was smooth and fast. This is in sharp contrast to my rather disappointing shave yesterday with a 1957 Superspeed, also with a new Personna blade. It left six nicks and some stubble along my jaw line. It's rare that I get a nick with a safety razor. My wife said I had some small red splotches on my cheeks, too, but I couldn't see them. This was the first time I tried this particular Superspeed but I've had others I liked and in fact my first razor in 1954 was a Superspeed (although I paid no attention to the name at the time). So which razor did I use today? No date code.
