You don' t need any big fillet knife or any of that stuff. I just use my little Gerber. Cut around the anus working it loose as deep as you can inside the pelvic bones. Once you have it cut good and loose and can pull on the whole works slightly to allow you to free it deeper. Longer fingers would help. Honestly, I do most of the free with my bare hands. Then I do the rest of the dressing. I don' t mount so I cut the windpipe loose about halfway up the neck and work around it alittle with my fingers to free it. Then when I cut the cavity open I reach up inside, grab the windpipe in front of the lungs and if you do it right you pull and the whole works lungs, guts, butt and everything will come out in one big piece. You' ll have to do some cutting of the diaphram and the organs along the spine, but it really does all fall out nicely. I work around the anus from the inside with my hands to make sure it free so it won' t bust off. If the bladder doesn' t come you can go in and free around it, pinch it off and pull it out. You' re right.. a lot easier to do than explain.
