> I think they intentionally put bad blades in the cheap razors.

Oh I think the likes of Gillette do far more devious things when it comes to the life of razors. For instance, I can almost swear that the blades on my Fusion razor seem to wear out much faster than the blades on my Mach 3, Sensor, Presto etc. (I've been nearly a lifelong Gillette razor user)

I think what Gillette does is to ensure that the lubricating strip wears out faster, thus causing discomfort while shaving and making one feel as though the razor itself has worn out.

Has your water changed (perhaps you moved around)? Deposits make the edge rough, some water will make more of them.

It is also somewhat more difficult to get a good lather with harder water.

It has, because I'm referring to nearly 20 years worth of shaving across multiple cities and localities. So yes, it could be a reason.
