Sounds like a really useful food gathering kit. Not sure I would bother with the scent. It is easy enough to remove the human scent with expedient items such as birch bark or smoke or pine pitch or skunk cabbage etc. The space could be used well enough to include a few flys for fishing or a bit more line or some sinkers or a little foam float.

To remove the shine from the picture wire, throw it in a smokey cool fire (burning leaves or such) then get it wet and let it start to rust then dry it out and oil it with something like bacon fat. The bacon fat will add a smell that will probably over-power any human scent and if you put it on really thin (while the wire and the fat are hot) it won't make too much of a mess. Take care that the time in the fire doesn't get it too hot. You only want to scorch and soot up the outside not ruin the temper.
