I had a Muhle R41 delivered yesterday, after my shave. Actually, it was almost after my lunch, but that's our postal service around here!
In my 3-and-a-bit years of DE shaving, I have owned and used a few razors classed as aggressive. Futur (if you turn the wick up), 39C Slant, Cobra Classic and a Gillette Old type.
In a fight, the R41 could take on all of the above razors at the same time and win.
I chose a blade and soap that are very familiar to me, and used the R41 this morning.
I have never shaved with anything as aggressive as this thing. I had to go really slowly, and concentrate 150 percent. It was more scary than the Cobra, and, if I'm being honest, bordering on the unpleasant. I did WTG, XTG, and then an ATG on my neck. I got a small weeper and a scratch on my chin, but nothing that the cold rinse didn't deal with.
The shave was not smooth at all, as there was quite a bit of tugging, but that could be me failing to hit the right angle, or even a mismatch with the blade.
Having said all this, on my face, with no ATG I was completely BBS, although slightly sore!
I think that I may leave it until next weekend before I try it again, as I dread to think what this razor could do if you were in a hurry before work.
