First, thank you for posting.
Production wise - I love the sepia effect in concert w/swing music for the classic art of straight edge shaving. Not only was swing befitting, but the horn bridge was even timed perfectly to transition into the shave.
Question: you sped up the stropping to quell viewer boredom, but I query... are you flipping the straight every stroke, or are you just lifting the edge every return? Can't discern at that speed.
