I'm going to stop at 35 shaves with the 74. I'm sure the blade will handle a few more shaves. And people with a lighter beard will get more shaves than I did. Most of the shaves were done every other day, with a few shaves having 3-4 days without shaving. At times, a couple shaves felt it starting to get tuggy, but would smooth out with the next shave. All shaves were BBS, with the last one needing a bit more strokes.
