Well, only speaking personally you understand, if it was left to me, I would have a beard as long as Nostradamus, because shaving isn't my idea of fun either.
However, the wife thinks rather differently, and as my middle name is Wimp. I just go with the flow.
lol Yeah I know what you mean, a new blade feels wonderful against the skin. I can probably manage a couple of months on one blade, but not much more.
The problem with new blades is, that they are very expensive.
Well I've been using my faithful Gillette Fusion for years now, gives a really smooth even shave, so I've had no reason to look elsewhere.
Mind you, that's for a wet shave of course, I can't get on with electric razors at all. They often leave me with a rash, and for me, they don't shave close...
