A lot of what makes the perfect field knife is what you are hunting. If it is normal sized whitetail deer and smaller, I prefer a fairly small knife with a blade length of 3 1/2 inches or less. If it is Asiatic buffalo, a blade length of 4 to 5 inches with more thickness to the blade is better. For elephant and hippo, a 5 to 7 inch blade of very sturdy metal stock is nice to have, along with a good axe. Andy Ivy's custom knife is perfect for the hunting he provides in Australia. Interesting that his initials (and those of his dad, Allan Ivy) are the same as for Artificial Intelligence. :D My initials, A.D., are the same as for Artificial Dumbness. :confused:
