I have recently acquired this vintage razor and I am really pleased with how it shaves. I find it more efficient than the Gillette flair tip and smoother than the knack Gillette razor which is supposed to be the same just having longer and thinner blue handle. What I do not like about this razor is the handle. Does anyone know if this handle is hollow? I am thinking of cutting just 3/4cm off the handle. Does a super speed from 40/50's shave similarly?
