i do it similar to these guys, grab his dank and cut carefully to one side then to the other down around his nutz. the the whole package is in your hads. i toss that to the side and then i open him up from just ahead of where you grabbed his dank. i cut him to the breast bone and thats it i reachy up in and grab just ahead of the goodies and pull and pull all his guts out then i remove his a hole. ive tried that butthole thing and it does work kinda. on big hardy maine bucks mine twisted into a pretzel in just a quarter turn, i threw that thing out and ill continue to use my knife from now on again. then i pull out his butt hole and what not and hes all done. i leave the live in the gut pile. who would want to eat that nasty ouil filter anywyas. i dont cutthe diaphram cuz we always have long drags through nasty woods. once i get to the truck ill slie the diaphram and take heart and lung
