Update So far, I have not started using a safety razor. I am trying to improve on my preparation, lathering technique, and direction of strokes while still using a Mach 3. As a side note, it is surprising how much less irritation I get now even with a Mach 3 by focusing on these things, and using CO Bigelow instead of canned. I used to only do N-S passes thinking this was always with the grain, but I now know this is not the case. Anyway, I'm hoping to try them both at some point, but I intend to try the Krona first as I have read that it is easier to get the correct angle with the Krona and I am trying to ease into wetshaving (i.e. learn one thing at a time and learn it well). Slow and steady is best for me instead of diving in headfirst. Reading Michael Ham's book is helping quite a bit. Thanks again for all the input.
