I recently acquired a Muhle R41,(my first open comb,but definitely not my last).
I find it to be an aggressive and efficient razor,worth every penny.
Up until the R41 I've used mostly my merkur HD and my Gillette red Tip
So here's the question:
What is the most aggressive closed comb/Safety bar razor you've used?
If you would like to mention a TTO as well as a 2 or 3 piece please feel free
