I'll start--- It's the Oster 76 hair clippers. They're powerful, barber-grade hair clippers that feel like you could saw a tree in half with them. I've read accounts of barbers using the same clippers for decades.
These things are so powerful that you'll be sure you're going to lob an ear off or chop your head in half, but I've never even nicked myself. It's practically a fear you have to get over at first...
Plus, if you shave your head bald (I do) but you don't want to use a razor, you can get a blade that cuts to a millimeter (#000000) which is as close to razored as you can get.
They seem to be the AK-47 version of hair clippers.
OK... your turn.
