The thing is, Mike, with an open comb (Merkur head on the Jagger handle) the first pass needs doing in shorter strokes, but then the second and third pass are pretty normal.
With a closed comb - forget it! Scissors first! Then rinse after every stroke. Should shift it with an extra WTG pass at the beginning
Obviously, that pic was to show where the growth would be, so you get an idea of stubble on regular shaves. The tache and goatee are longer than that now. It's up to about 80mm
My Tech wouldnt do it easily. My Slim on 9 would do it more easily. My Regent would do it pretty easily. All are closed comb razors, but the King of them is my Regent. It has as much blade exposure as my R41 or Grande.
Growth like that are why OC razors were invented, I believe. They align and funnel the hairs to the blade.
