My Dad has a Benchmade Hidden Canyon. He cleaned a deer and a pig the other day, and it will still shave some hair. It is slightly shorter than what you were asking for though. I have the Benchmade Grizzly Creek. It is a folder with a skinning blade (i guess that is what it is), and a separate gut hook. The blades are crazy sharp. I have cleaned a couple elk, few deer, and lots of pigs with them. I also have an outdoor edge razor pro with the disposable blades. I use this when I don't want to ding up the benchmades on bones and what not.
