The pliers method is good too- but from what I hear can have a higher chance of causing infection due to it being fully exposed instead of just the tip. Also, if you have a aggressive cock there is still a point there to stick in your leg, with this method it is completely blunt and the friction from a saw causes little to no bleeding.
My wife and I did our large rooster last week using the plier method. There was very little blood, just a couple of drops. Anne put some Neosporin on it as soon as I removed the spur. Nothing to it. I've used the plier method several times, and it's actually easier than it looks in the video. First wrap the rooster's head with a towel while holding him. All you do is put pliers on it with a fairly tight grip; wiggle up and down a few times until it snaps loose, and take it straight out/off. Nothing to it.
