This forum is filled with scholarly analyses of the various classic razors-the blade angle, the weight of the handle/head, the geometry of the head, etc. etc. As far as I can tell this information was not provided by Gillette (et al). Before this information was available, and before written/online reviews how did a man select a razor given the fairly significant differences between them? Did they just try one?-that could have gotten expensive given the inflation adjusted prices, rely on friends, etc. Any ideas?
