RE: Field Dressing deer
First, get a wyoming knife. Make the slit just below the sternum and put that knife in and zip it right down to the pelvis. It opens them just like a zipper. When cutting around the anus, go as deep as you can. Cut the diaphragm between the lungs and stomach, reach up and cut the windpipe as high as you can, and yank the whole mess right out.
The wyoming knife is the best purchase I've made in a long time. It also cuts skinning time way down and I even use it to separate the cuts of meat on the hind quarters. Check it out.
