cozzyb said:main thing to watch for is pressure, as when you are new to it you will be tempted and muscle reflexing to shave like a gillette multi blade, and it tends to be rough on the skin/cut your skin.
JUst go light, if you want to force yourself for a while till you are used to it, try shaving by holding just the end of the handle and nothing else, just don't let your wrist be too floppy or you may cut yourself.
