re: Shave Club reviews:

The key thing is keeping your blade sharp and dry. I go old school with a badger hair brush and have a stand to let my razor dry out between uses. That at least doubled my blades life. Then I found the Razorpit sharpener doohickey (see the link below, it is discussed half way through the article). I use it once a week and a blade lasts me +3 months now (I shave my face and head). Definitely recommend getting one of these because it will pay for itself within 6 months.
