I am devastated!Well ... I'm going to disappoint you here. 95% of my shaves are using a Simpson schizophrenic synth, MdC Original (a gift (very much appreciated!) from @Jake only use another (ToBS Lavendar creme) when I'm in a hurry) and my repaired formerly broken Merkur 37. Blade: Merkur or Voskhod.
Post shave only cold water.
