@Dashtop few reasons...
1) electric razors are messy and you get hair everywhere. Only really works if you do it before a shower or else you are covered with hair
2) this one is minor, but razors make the cut hairs sharp. this can sometimes give you hair splinters
3) most important, a closer shave
4) it helps that you smell so nice when done from soap.
@freemo you have your reasons then. Cheers!
