So I just had my first shave with my new 40's style super speed (notched with no date code). Comparing it with the '56 flare tip and the black handle '73 that I have, I found it a tad more aggressive with more blade-feel. I thought it would be more mild. Granted, this is one shave with my go to sharp star blade. I liked it, but not quite what I expected. Is this the one people often prefer? What has been your experience?
