I was using straight jojoba oil as a pre-shave. But the last couple of days I've been using a 1/2 1/2 mix of jojoba and liquid vitamin E. The vitamin E seems to have lubed things up a bit.

Usually it takes a bit to rinse off the straight jojoba on the blade, but with the Vitamin E mixed in there, it slips off easily. Seems to work similarly on my face too!
