Need some help here an electric razor. I know, I know there is a good reason for this

My Grandpa has shaved his head with a razor for nearly as long as I can remember. Unfortunately, he has recently gotten to the point where he no longer can do this with an actual razor. Like any true gentleman, he prides himself on a sharp appearance and self reliance.



Can anyone recommend and good quality electric razor for shaving your head. Money isn't an issue, quality is.



Thanks for any assistance you can provide. I was pretty saddened by the need to ask the question.
