What do you use to shave?

Couldn't find Sensor blades anymore, so I made the move to Mach 3 a month ago. I like it.

The Onion had a piece a few years ago on the blade wars between Gillette and Schick, including a "quote" from the Gillette CEO:

"I dont care if we have to mount the thing vertically on the handle, ours will have a fifth blade!"
