As in title. The obvious answer is probably pick one of the sharper Gillette blades and be done with it, but I am curious if anyone is using the Red Tip Superspeed or the Lady Gillette regularly and is not using a Gillette blade.
I find the Red Tip quite mild since I have spent a lot of time with a Fatip - the Lady Gillette will almost certainly require something like a Bic or Perma-Sharp for my liking. These responses are mostly confirming that people use blades on the high end of sharp with these vintage razors.Something to consider with the two razors. The Red Tip is more aggressive than the Lady Gillette. I could run a Dorco through my Red Tip and think, "That was an okay shave." But a spin through the LG and I'd be wondering if the blade was dull. A Feather in the milder razor would suit me; while one in the Red Tip would scare me.
That's not to dissuade you from trying any blade in either, just that it makes assessing a particular blade's performance a little more challenging.
