I'm not sure if this topic has already been discussed. If it has, perhaps you can provide the name of the topic as a link in your answer. Anyway, realizing that YMMV, here it goes. I shave with a Gillette adjustable (not sure of the exact model name; I bought it about 40 years ago and it still works pretty well) and I usually have the setting at 4. I prefer using either Astras or Personas. If I were to take a step into the kingdom of bravery and splurge on Feathers, I'm guessing I would probably have to turn the setting down to at least 2 if not 1 instead of keeping it at 4, lest I scrape all the skin off my face. In general, will I get the same effectiveness with a Feather blade at a more sensitive setting than I would with a slightly less sharp blade at a higher setting? If I choose to stick with Astras and/or Personas, what is the ideal matchup as far as a razor is concerned (either fixed or adjustable) at a price of under $45? Thank you in advance for your responses.
