I am also making naked snake's knife. Although his knife is simply a GI tanto it has custom aspects. Such as the serration and a curved blade instead of straight edge. I deliberately did not include the cotton handle grip due to having to show the slight raise in the centre of the grip. This is because it thickens the handle and makes it similar in grip to a rounded diamond like shape once the thing rope is tied around it, making it more comfortable and secure in Snake's hand.
