Reddit mentions of Fonex Aftershave Cologne, Attractive, 27 Ounce

To get a really close "baby butt smooth" shave then you will usually have to finish with an against the grain pass when using a DE safety razor. Getting the Muhle R41 (which I do not own and have never used) won't really help you with getting the same smoothness from only a with the grain or across the grain pass. I think you'd just be more likely to get razor burn. Using a mild razor while you are still perfecting your technique will just help keep you from getting razor burn and make your shaves more enjoyable. If and when you do want to upgrade to a better razor and retire the old plastic WS then look at the Edwin Jagger DE89. It is on the mild side but reasonably priced and the usual recommendation around here for a first razor. The slightly different model numbers just denote differences in the handle, if it has crosshatching or not. Or if you really want to try an aggressive, get the Muhle. As we say here, your milage may vary so whatever works best for you, just do it.

You should definitely try a blade sampler pack. While most razor blades will do the job some brands will just be better (less tugging, less burn, smoother shave, etc) for you. For me, my favorites are Gillette Super Platinums in the blue packaging and Bolzano Superinox. I can only find one blade sampler pack on Amazon UK and it really sucks. Instead maybe get this one from Shaving.ie. I haven't ordered from them myself but they have a good reputation here and I've seen them recommended a lot. Maybe add a pack of Bolzano, Astra Platinum, and/or Shark blades.
