I was tempted to post with tongue in cheek and say,"Because they get tired." Now that I've gotten that out of the way ..... there was a fable that the edge needed 24 hours or so to return to normal before being used again. This has been proven to be false if I am not mistaken.

In the days when this was a common belief razors were sold in sets of 2, 4, and 7. The more wealthy customers got them I guess. A practical reason to have a rotation today is that you can always be sure to have a shave ready razor to use should one need attention or if an accident should happen. Dropping the razor or dinging the edge on the faucet. Then there is the RAD which many of use suffer from .... or enjoy... depending on how you look at it.
