I too am a scruff. If I average out over the ~10 years I’ve been shaving, the frequency would lie somewhere between fortnightly - monthly.

I think it’s for this reason, and the fact that I use shampoo and conditioner on my face if I have more than a week’s growth, that I’ve managed to keep a remarkably soft beard. If I do shave, I use a Mach 3 and whatever shaving gel happened to be on special at the super market. I’ve been tempted by the old school shaving equipment such as the brushes and soaps mentioned, but I’ve get to get around to purchasing any of it.
