I found out this morning that if you're clumsy, uncoordenated, and stupid enough you can cut your chin while shaving with a Mach 3 SAFETY razer. What a clutz!!! 3 nice 3/4" long slices on my chin. Bleeds like crazy too. Had to put on a bandaide to stop the bleeding. You should have seen my hands a couple weeks ago when I helped my brother in law fix his dock. No wonder my wife won't let me use any power tools! I think I'll spend the day in my recliner.... I hope I don't close it on my feet. HA!
