Re: Oh dear, I just chopped my leg! (scenario)
Use only with EXTREME caution. If you tourniquet a limb, you will cut off the blood supply to everything distal to the tourniquet - goodbye limb!

Firm, direct, localised pressure is the way to go in most cases, and as others have mentioned, elevate the limb. Then get to hospital ASAP.
On an aside, if you're heading into the woods with sharps big enough to do some real damage (ie. and axe or a billhook), then a large bloodstopper bandage or military type field dressing in your FAK, is a really good idea.
