ae1pt:
I have five straight razors: a Kinfolks, a Crown, and three Gencos, all purchased at antique stores/malls. If one is careful and looks for razors which have not been abused, these relics can, indeed, provide a good and satisfying shave once their edges are properly set As you pointed out, however, it DOES take time. Accordingly, I typically use mine only on the occasional Saturday morning when I can properly invest in the indulgence.
Strops and hones may also be found at the antique stores and malls, at least that's where I found mine.
