Can anyone tell me what the length of the sharpened portion of the blade is on this knife? I know the blade length is advertised as 4.125, which I assume as being by AKTI standards? I am looking to find this out because I am considering buying one, and would like to be able to carry it in the woods, and except when fishing or hunting, I can't carry a knife, having a blade, the edged portion of which is greater than four inches in length(CGS 53-206). I would like to get as much utility as possible out of it.
