It's easy to carve a turkey using an electric knife, I've done it many times.
You need to wait about 15-20 minutes after you've cooked your turkey for it to obtain its maximum moistness. Plus, it will make the whole carving process easier. Some sites recommend you wrap it in aluminum foil as it stands. Use this time to wash up so you're not touching your guests' food with dirty hands.
Okay, you've been patient. Your guests are hungry, though, so it's time to start cutting up that bird. Use the fork to stabilize the turkey as you cut, and remember to be gentle for the best results!
