A few years ago I read that razors do not get dull from shaving, but putting it away wet. Drying is supposed to make a razor blade last much longer. I decided to see just how long.
The last time I changed blades was 15 September 2011. The blade is starting to drag a little and not get a good close shave. That would be about 21 months.
Experiment has been interesting and a bit of fun. Nice getting close shaves for so long and saved a bit of money along the way. This ends my toying with this.
