Some people use a old knife and a rock to split it. I use a small wire saw made for this. just cut around the a hole slide one handle through the pelvis pull up and cut through in about 3 seconds. I bought a saw yesterday with a handle and end gaurd to prevent puncturing the bladder, it looks like it will do better. One of the hunters on our lease will lay the deer flat on its back drop down and pop the pelvis by landing with his knees on each of the hind legs. I havent perfected that move yet.
