I've never dressed out a big game animal before so please forgive me if the following questions seem silly. What tools do you recommend for field dressing a deer? I'm assuming that I'll at least need some kind of hunting knife for gutting a deer and another (or the same?) for skinning. I've also seen knives advertised with a "gut hook". Presumably this is used to open the deer up without puncturing the intestines or the bladder. Does this device really work? Thanks.
