Just got my Merkur 37c slant today and took it for a short spin with a feather blade. An ATG and a XTG shave quicky. Initial impression is that it is a good shaver and less aggressive than the Muhle R41 2013 that I use with the same feather blade. A long trial with the 37c should be able to tell me how close it will come to the Muhle R41 for closeness and how long the shave lasts.
I have no idea how the 37c slant got such a rep for aggressiveness as it shave like a regular DE non slant to me. If you are used to DEs and have good technique this could be a very nice DE for you. Goob knurling on the handle so the grip feels very secure.
