Today I shaved for the fourth time with a safety razor since my first try a couple of weeks ago. There was less irritation this time but not as close as the other times. I did 4 mainly WTG reduction passes. It appeared to take too long for all this (1 hour) and I'm still making a mess around the sink. What should I concentrate on next? Any advice and tips would be much appreciated. I need to look into acquiring some other blades than the Merkurs! Finally, I have noticed that the blade is not scraping the lather clean like in the Mantic video. It appears to leave much residue behind. Is this something that I should be concerned with? Thanks in advance!
