I use electric. A major reason is that being visually impaired I can’t see my stubble – so I wouldn’t know where to shave, especially when my face is all wet.
So I have to use the shaver and feel where still needs doing. Its not perfect I must admit.
The alternative that was proposed on Dave Gorman’s “Genius” radio programme was “a whole face bespoke mask lined with razor blades requiring just a few movements making shaving quicker and easier”. Unsurprisingly it didn’t win!
