My exploding razor knows secrets
You mentioned another important point.Amazing - he does no skin stretching at all and, given how loose his skin is due to his age, I would expect him to cut himself, but he does not. I would watch that and swear his technique was terrible but it obviously works for him. A very interesting video and certainly something to think about
Many shaving tutorials demonstrate various yoga-like "skin-stretching" poses—especially for those who shave the left side of their face with their non-dominant hand.
And Billy Hukin only used a little bit of "making faces" techniques - occasionally smiling/raising the chin/blowing a little... to stretch the skin, truly demonstrating how pure "traditional shaving" is.
