Sounds like you guys have a lot of great ideas. However, once again, I believe there is a huge void in the kits mentioned.
As I've said many times before, I consider a gun an essential part of any survival kit. (assuming longer term survival scenario) If you say they're illegal in your area, well then, you're not really talking about a true survival scenario anymore, are ya?
If I were on the brink of starvation, I doubt I'd care about some illegal firearms charge once I got back to civilization. Many people suggest a .22 rifle, but in my area I swear we have more deer than small game. So I'd want something powerful enough to easily harvest deer. (and it will kill a rabbit just as dead as a .22.) Granted, I'd probably bring both- a good rifle for the bigger stuff, and an accurate .22 pistol for smaller game. I have heard people decry pistols as worthless in the woods, but I figure they never learned all the improvised tricks to make them more shootable/effective.
And even if you still can't justify a gun, then I'd be thinking about what I'd need to make a bow and arrows.
Every culture in the history of the world has considered the bow essential for survival. How come no one here has mentioned it? I can't think of any culture that lived solely on fish and whatever small critters they could trap. I guess you've already got the blade to carve it out, and string, but I'd be mighty tempted to bring along a stack of steel broadheads made from simple barstock. (for compactness and ease of affixing to a shaft) The American Indians traded many pelts for steel arrowheads, so obviously they are well worthwhile over anything that can be improvised in the wild. (Of course, they then replaced their bows with GUNS as quickly as they possibly could as well. See the first paragraph.

If it helps you, bring it. The important thing is to survive, and the mental part of survival is very important, that why I always carry a photo of my family.
