Meet the Razor Saver (no not the one as seen on TV)
Basically that black thing is your razor sharpening itself on a metal plate thingy and it sharpens it for you when I run it over water.
Its pretty inexpensive and supposed to make my blades last 5x longer then usual. Which is good because let's face it--we go thru those things quickly.
Pros: It sharpens and its safe to use.
Cons: your lady razors (aka the ones with teh HUGE handles) dont' fit in here. Its made for a standard razor; thinks disposable ones. So I just take off the blade and run it carefully over the metal plate.
So give it a shot! What do you have to lose aside from less trash!
Here's where I got mine: Sustainable Village.
