I am a collector of GEMs, I have quite few 1912s, see below for proof :) .
I've just got into the micromatics.
I didn't start off on the right foot, I'm down to my last personna blade, so for my first MM shave I used a 3 shave old personna blade.
Everything went good until the first pass on my chin. I have tough stubble there so I think that did the blade in and blunted it enough to ruin all later passes.
Second shave I use some blade I normally can't stand, some carbon one that I hate in the 1912. I did OK in the MM, better than I remember it doing in the 1912, but still not a great shave.
Third shave I used my last new personna and had a three day growth as well.
WOW, it cut through like nothing else! I didn't seem to have to work as hard at it either. It's like a feather in a fatboy wound up to 11! Perfect for me.
Unfortunately I wasn't careful and I've had a few drinks before shaving so I got a couple of cuts, so I only did two passes. I also deciided why not face lather? why not use this soap I usually don't like? In other words a very haphazard and careless shave.
No ATG, no touchups like I have to do with every other DE or 1912. No j hooks or blade buffing like I usually have to do to get my chin smooth.
But, with those simple two passes (WTG, XTG), I have never ever got such a smooth chin and upper lip than I do now with just two passes WTG and XTG.
The offender in question is the 1929/30 clog pruf at the top right. I haven't tried the open comb 1929/30 version at the bottom in the centre yet.
