I am mapping out my favored "GO-TO" shaving method as we speak.
I prefer a very close shave and a smooth result, so it seems most of the lower number blade cartridges tend to leave more stubble, which is not very efficient for me. No one wants to have shave twice. With all of the noise surrounding the Mach 3, I decided recently to give it a try and it didn't seem to consistently give me a close shave all over my dome.
However, the 5 blade cartridges seem to do rather well, but I'm still exploring the various shaving methods available.
Anyone have any new and improved insights as to your favored razor???
