I would like to know the forum's thoughts regarding how much effect the pressure of the razor against the face while shaving has on the longevity of the edge before it requires a touch up.

I recently realized that I was using much more pressure than necessary to get a good shave. No irritation or burning, just more pressure than necessary. I lightened up and I still get a good shave.

How relevant is pressure to the useful life of a shaving edge?

Thanks in advance.
