I can't say whats best... However, whitetails aren't big critters... and going from the field to the table... I think the knife really matters, cause at each step, I find that my needs vary so much... I don't know of a best one (but best ones)overall, but here's my way of doing it... They to each knife is being SHARP!!!
I've field dressed deer with everything from a victronix swiss army key chain knife- to using a K-Bar.
(these are in the pack/pocket knives)
My favorite is an old boker (high carbon) gentlemans 2 blade knife... That would hold an edge!!! made th job go easy
(but I lost it, time to replace it)
However butchering/quartering and deboning; is different work altogether... for that I use a couple of cheap boning knives
(bought at a dollar store- these are usually at camp/truck where I hang the deer and proceed to to render into pieces managable enough to put on ice in the cooler) to get my deer into parts and then go to the Zwilling J.A Henckels kitchen knives
(At home in the kitchen- where the paper, tape, foil, and meat grinder are...) to acually butcher the parts into cuts of meat...
I think whatever you use, the key is a sharp blade! What system you use it is your choice! I personally like arkansas stones
(endin with a black stone) but if'n you don't know how to use em there's so many systems that work as well or better... from gatco's to paper wheels.... tormek, Lansky...etc
I think for the most part its easier to learn and understand how to sharpen a knife and *how* make a knife sharp... doesn't matter what knife you buy, at some point you need to be able to sharpen it...
here's a good website with tons of info with various systems and too much info...
