So I’ve placed the Merkur blade into the 39C, and had a headshave. It does look like the blade is torqued/twisted within the housing. Oooh aggressive.
The 1st shave was fantastic! WTG, ATG, Touchup. Baby smooth; very little burn (probably from bad technique). The 2nd shave the next night however had very different results. Maybe the stubble hadn’t grown enough, or maybe my skin hadn’t had a chance to rest enough.
Burn! Super alumblock burn!
I’ve been logging my results with different blades. And it turns out, for ATG passes, most blades are only good for one headshave, with the exception of Feathers (2-3).
