Shaving - cheaper and greener

I became tired of spending 3 or 4 dollars per blade for my gillette mach 4. On the advice of a friend I acquired my grandpa's old safety razor. Not only do the blades cost only about 15 cents, but they last for 5-10 shaves, and don't create the unnecessary waiste of the plastic cartriges. I did end up with a few minor cuts on my neck when first trying it out, but I feel like I actually get a better shave. I used to get little bumps on my chin and neck from ingrown hairs (a result of the multiple blade - lift & cut system), but with the single blade I take two or three passes to get closer and no longer have the problem.
